  • Ruthenium catalyzed synthesis of five-membered
           O‑heterocycles
    • Abstract: Publication date: Available online 13 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Navjeet Kaur Nitrogen, oxygen, and sulfur containing heterocycles have a wide range of biological activities. Metal catalysts are used in organic reactions with high activity. New strategies have been developed for the preparation of heterocycles in the last decades. The metal catalyzed synthesis of heterocycles is becoming an important and highly rewarding protocol in organic synthesis. In this review article, the synthesis of five-membered O‑heterocylces is presented using ruthenium catalysts.Graphical abstractUnlabelled Image
       
  • A 9‑chloro‑5,6,7,8‑tetrahydroacridine Pt(II) complex induces
           apoptosis of Hep‑G2 cells via inhibiting telomerase activity and
           disrupting mitochondrial pathway
    • Abstract: Publication date: Available online 13 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Shu-Long Wang, Zhen-Feng Wang, Qi-Pin Qin, Ming-Xiong Tan, Dong-Mei Luo, Bi-Qun Zou, Yan-Cheng Liu In the present study, one novel Pt(II) complex, [Pt(CTD)(DMSO)Cl2] (1) with 9‑chloro‑5,6,7,8‑tetrahydroacridine (CTD) as ligand, was synthesized and fully characterized. The CTD Pt(II) complex 1 was an anti-cancer drug candidate, and it possessed potent therapeutic efficacy for hepatocellular carcinoma (HCC). To explore its mechanism against HCC, Hep‑G2 cells were treated with the CTD Pt(II) complex 1 in vitro. MTT assay showed that the CTD Pt(II) complex 1 had inhibitory activity against five human cancer cells, such as SK‑OV‑3, Hep‑G2, NCI‑H460, MGC80‑3 and HL‑7702, and it displayed the strongest inhibitory activity against Hep‑G2 cells with an IC50 value of 10.48 ± 0.83 μM. Moreover, the CTD Pt(II) complex 1 also exhibited selective cytotoxicity toward the cancer cells. In addition, the CTD Pt(II) complex 1 had low toxicity against non-cancerous HL‑7702 cells. The CTD Pt(II) complex 1 caused mitochondrial dysfunction, leading to the down-regulation of bcl‑2 protein and up-regulation of some mitochondria-initiated apoptotic proteins (including apaf‑1, cytochrome c and bax) in Hep‑G2 cells. Taken together, the CTD Pt(II) complex 1-triggered Hep‑G2 cell apoptosis was mainly mediated via interaction with c‑myc promoter and disruption of mitochondrial pathway. Collectively, our findings supported that the CTD Pt(II) complex 1 could be used as a potential drug candidate for chemoprevention or chemotherapy of HCC.Graphical abstractThe CTD Pt(II) complex 1 triggered Hep‑G2 cell apoptosis mainly through inhibiting telomerase activity by interacting with c‑myc promoter elements and disruption of mitochondrial pathway.Unlabelled Image
       
  • A novel Lindqvist intercalation compound: Synthesis, crystal structure and
           hydrogen evolution reaction performance
    • Abstract: Publication date: Available online 13 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Qingbo Shen, Chunjing Zhang, Mo Wang, Haijun Pang, Huiyuan Ma, Xinming Wang, Lichao Tan, Dongfeng Chai, Yan Hou, Bonan Li A new polyoxometalate (POM)-based inorganic-organic compound [Cu2(bimb)2(ox)](W6O19)·4H2O [bimb = 1,3-bis(1-imidazoly)benzene, ox = oxalic acid] (1), has been synthesized by hydrothermal reaction, and characterized by IR spectroscopy, single crystal X-ray diffraction, and powder X-ray diffraction. It consists by porous metal-organic 2D positive layers [Cu2(bimb)2(ox)]n2n+ and the W6O192− clusters serving as anionic pillars that make [Cu2(bimb)2(ox)]n2n+ positive layers aggregating around W6O192− clusters to achieve a novel porous intercalation structure. The compound 1 show high electrocatalytic activity for hydrogen evolution reaction (HER) with low overpotential (η) of 146 mV at a current density of 10 mA·cm−2, which is superior than the most of reported POM-based electrocatalysts. This is probable due to its unique porous intercalation structure that H+ can diffuse easily through the pores. Also, the HER mechanism was discussed, and the electrocatalytic reduction of NO2− ions was studied.Graphical abstractThe first Lindqvist isopolyanion-based compound with an intercalation structure was obtained and further applied in the hydrogen evolution reaction (HER), showing high catalytic active toward HER.Unlabelled Image
       
  • Preferential coordination of ruthenium complex as an electroactive
           self-assembled monolayer on gold substrate and its application in sensing
           of dopamine
    • Abstract: Publication date: Available online 12 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Kalil C.F. Toledo, Juliano A. Bonacin Self-assembled monolayers (SAM) are molecular assemblies ordered on a solid surface. In general, they are formed by the reaction of an alkyl-thiol molecule and a gold surface. Alkyl groups do not have additional functionalities in this case. On the other hand, the detailed design of electroactive layers able to be assembled on gold surface can transfer all electrochemical behavior to this surface and thus, an inert surface can have defined and modulated properties. Motivated by this approach, our interest was to evaluate the preferential coordination of the complex [Ru(H4dcbpy)2Cl2] with the 4‑mercapto‑pyridine ligand through the pyridine portion. To achieve this specificity, the ligand was previously attached to the surface of the gold electrode by the thiol portion. Moreover, the electrode modified with the electroactive self-assembled monolayer (E-SAM) was used in sensing of dopamine. Based on the electrochemical studies it was possible to observe that the gold electrode modified with the E-SAM of ruthenium complex (Ru‑4‑mpy‑Au) had an increase in the resistance to charge transfer (Rct = 274 Ω) when compared to the bare gold electrode (Rct = 19 Ω). On the other hand, the charge transfer rate constant is 104 times faster than for the bare gold electrode. These results suggest that the Ru‑4‑mpy‑Au electrode can be used for sensing of molecules through the electrocatalytic process of oxidation. The Ru‑4‑mpy‑Au electrode shows the best results for linear range (0–400 μmol L−1), and the lowest potential of detection (0.2 V vs Ag/AgCl) and limit of detection (3.3 μmol L−1) when compared to the other electrodes that were studied.Graphical abstractUnlabelled Image

  • In situ preparation of CeO2 nanoparticles on the MCM-41 with magnetic core
           as a novel and efficient catalyst for the synthesis of substituted pyran
           derivatives
    • Abstract: Publication date: Available online 10 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Hamid Reza Saadati-Moshtaghin, Farrokhzad Mohammadi Zonoz An inexpensive, environmentally-benign, and magnetically recoverable nanocomposite consisting of magnetic core and MCM-41 mesoporous silica shell which was synthesized by using Rice Husk Ash (RHA) as the silica source was prepared. Subsequently, the CeO2 nanoparticles were synthesized and immobilized on the magnetically recoverable MCM-41 by impregnation method. The synthesized nanocomposite was characterized with FT-IR, XRD, FE-SEM, TEM, ICP and VSM. The obtained new nanocomposite demonstrated a catalytic performance in the synthesis of tetrahydrobenzo[b]pyrans at the condensation condition under solvent-free conditions. The nanocomposite catalyst could simply be recovered from the reaction environment by using an external magnet field and be reused five times without a remarkable losing in catalytic property.Graphical abstractUnlabelled Image

When exposed to HS−, the synthesized probes showed significant color changes from yellow to red and remarkable increase of fluorescence intensity (over 80-fold). What's more, the interaction of host-guest could be completed in 2 min. However, no clear color and fluorescence intensity changes were observed in the presence of other anions (AcO−, H2PO4−, F−, Cl−, Br−, I−, SO42−, SO32−, CO32−, Cys and GSH). The synthesized colorimetric fluorescent probes could detect HS− rapidly and conveniently. Cytotoxicity studies indicated that the synthesized fluorescent probes were low cytotoxicity in Hela cells and may be used to detect H2S level in vivo.Graphical abstractFour crystals based copper(II) complexes were obtained and the molecular structures were all characterized by X-ray diffraction.

           base Cu(II) complex as the fourth type urease inhibitors
    • Abstract: Publication date: Available online 3 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Xianxian Chen, Chenyi Wang, Jiajia Fu, Zhaowei Huang, Yaoyang Xu, Shaoqi Wang Four kinds of Schiff base Cu(II) complexes (the fourth type of novel urease inhibition) were synthesized by the coordination of transition metal Cu(II) ions with aldehyde amine type Schiff base ligands, they were aqua-(5-methoxy-2-((((pyridin-2-yl)methyl)imino)methyl)phenolato-N,N′,O)-(nitrato-O)-copper(II) (1), catena-[(μ2-Isothiocyanato-N,S)-(4-chloro-2-(((pyridin-2-yl)methylimino)methyl)phenolato-N,N′,O)-copper(II)methanol solvate] (2), di-μ-bromobis[1-({[2-(piperidin-1-yl)ethyl]imin o}methyl)naphthalen-2-olato]-di-copper (II)(3) and tetrakis(m-bromo)-bis(m-4-chloro-2-((2-(piper idin-1-yl)ethyl)carbonoimidoyl)phenolato)-tri-copper(II) (4), respectively. The structural characterization of four complexes was performed by Infrared spectrum and X-ray diffraction. The inhibitory effect of complexes on Jack bean urease was studied by phenol red method, and the kinetic mechanism of complexes inhibition of urease was investigated by Lineweaver-Burk plot of reciprocal. The results showed that IC50 values of four complexes inhibit Jack bean urease are 5.36 μM, 8.01 μM, 2.25 μM and 1.00 μM, respectively, which are much lower than that of the acetohydroxamic acid (27.7 μM) coassayed as a standard urease inhibitor. It has a strong urease inhibitory activity and is a promising urease inhibitor. The inhibitory mechanism of complex 1 and complex 2 on the Jack bean urease belonged to mixed-type inhibition, and the complex 3 and complex 4 is anti-competitive inhibition. Molecular simulation docking calculations show that complexes 3, 4 can form a more stable urease inhibition binding model than complexes 1 and 2 through salt bridges with amino acids, which also theoretically explains the results of experiments on inhibition of urease activity in vitro.Graphical abstractUnlabelled Image

  • Studies on twist bent core zinc (II) methacrylate supramolecular columnar
           hexagonal phase mesogen derived from azobenzene moiety and its photo
           luminescent behaviours
    • Abstract: Publication date: Available online 2 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): R. Keerthiga, T. Kaliyappan, P. Kannan A class of Zn(II) polymethacrylate mesogen was tailored with photoluminescent property as well as high thermal stability by wrapping the Zn(II) metal in polymethacrylate mesogenic core. The versatile thermal stability of the mesophase was accounted by long chain terminal alkoxy groups and jacketed Zn(II) metal core. The extended stable mesophase with rise in temperature was achieved by excellent coordination between the supramolecular ligand with that of metal core. The Schiff base was prepared by treating (1-bromo (4-dodecyloxy azobenzene)) with octadecyl amine in ethanolic medium. The Schiff base obtained was polymerised with methacrylic acid (MA) in presence of AIBN as free radical initiator. The supramolecular mesogenic ligand (PMA-L) was further complexed with Zn(II) acetate in 1:1 M ratio. The Zn(II) supramolecular mesogen was extensively characterized by 1H NMR, 13C NMR and FT-IR. The mesomorphic behaviour was studied by XRD diffractogram, DSC, POM. The Zn(II) supramolecular exhibits columnar phase transition due the molecular stacking in disc shape. The disc shape mesophase of the Zn(II) supramolecular mesogen was achieved by sandwich pattern of metal core between two organic ligands arrangement. The photo physical character of the Zn(II)polymeric mesogen was studied by absorption and fluorescence spectral method.Graphical abstractUnlabelled Image

Al-Sehemi, Mehboobali Pannipara A simple hydrazine carboxamide derivative with intramolecular charge transfer and aggregation induced emission (AIE) properties have been designed and synthesized. The derivative (Probe 1) shows typical AIE characteristic emission in THF-water mixtures and emits yellowish orange color on reaching the water fraction 98%. The probe molecule show selective sensing response for Cu2+ ions via fluorescence turn-off mechanism in aqueous media over other metal ions. The emission changes towards Cu2+ ions that could be clearly observed by the naked eyes under 365 nm UV lamp promote the probe molecule as a promising candidate for practical utilization. Furthermore, from the fluorescence titration data, the detection limit for Cu2+ ions was found to be 0.44 μM.Graphical abstractUnlabelled Image

    • Abstract: Publication date: Available online 1 November 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Arpita Desai, Hetal Roy, R.N. Jadeja The calix-salen cavitand is found to bind Cu2+ preferentially among the 1st transition series metal ions and alkali metal ions. The marked change was observed in the absorption maximum of cavitand on recognition of Cu2+ ion. The binding of copper ion also reflected in the visual colour change from yellow to green. The binding was selective for Cu2+ with little interference from iron. From Job's plot it is found that the cavitand binds copper with 1:1 stoichiometry which is further supported by DFT calculations. We synthesized the copper-cavitate and characterized it by spectroscopic techniques. Cytotoxicity assay using MTT was performed to determine anti-proliferative efficacy of copper-cavitate on IMR 32, MCF-7 and L132 cell lines. The copper cavitate is found to be potent antineoplastic agent. The same has been confirmed by gene expression studies.Graphical abstractUnlabelled Image

The corresponding heterometallic ZIF was synthesized by mixing manganese(II) and cobalt(II) ions in the presence of 2-methylimidazole as linker. Calcination of the intermediate ZIF in air affords the nanosized mesoporous manganese cobaltite with spinel crystal structure. The obtained nanomaterials were characterized by a combination of physico-chemical and spectroscopic techniques.

Based on the efficient peroxidase-like activity, the mesoporous MnCo2O4 nanocatalyst/ODP substrate system was used for the determination of H2O2 concentration in aqueous solution. This report also includes the result of detailed kinetic study of the catalytic oxidation reaction. The mesoporous MnCo2O4 with large surface area showed higher catalytic activity in oxidation of OPD compared to that of natural peroxidase as well as the individual components Co3O4 and MnO2 nanoparticles.

  • Nitrate ion effect on gold nanorods plasmon resonance behavior: A
           potential chemical sensor
    • Abstract: Publication date: Available online 24 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Alireza Akbari, Minoo Derakhshesh, Majid Ebrahimizadeh Abrishami High sensitivity of surface plasmon resonances (SPR) in noble metals to the surrounding refractive index variations in the environment is a powerful bio-sensing technique. Here, we report the development of a simple colorimetric detection method for nitrate ion in water using gold nanorods (Au-NRs). Au-NRs suspension with the average aspect ratio of 3.5 was prepared by a modified seed growth method. According to the safety limit standard of nitrate amount in drinking water, different volumes of 10 mg/l nitrate solution were added to the Au-NRs suspension. Adding the nitrate group to the suspension resulted in turning to the nanorods with lower aspect ratios and finally spherical nanoparticles. The concentration of nitrate in water can be determined by monitoring with the naked eye and a UV–Vis spectrometer. It was shown that lower volumes of nitrate additive (25 μl) was a better identifier than those with higher volumes (50–150 μl). The color of Au-NRs suspension turned somehow from faint pink to purple after two days of adding 25 μl of nitrate solution. In addition, the UV–Vis absorption peak corresponding to longitudinal SPR (LSPR) blue-shifted from 814 nm to 712 nm after two days while the peak corresponding to transverse SPR (TSPR) showed a slight shift from 519 nm to 521 nm. Much more effect of nitrate group on LSPR than TSPR showed that nanorods are better identifier and biosensors than spherical nanoparticles. Decomposing and converting the Au NRs to sphere particles and lowering the initial aspect ratio of NDs in presence of nitrate ion is reported for the first time, but more works needed for talking about its mechanism.Graphical abstractUnlabelled Image

Two types of hydrated and sintered CoF2 NPs were prepared with different ratio by changing water to surfactant ratio while keeping the temperature constant at 22 °C. The hydrated CoF2 NPs were sintered at 400 °C under inert atmosphere at 5.0 millibar pressure for 3 h in vacuum chamber in order to obtain sintered CoF2 NPs. The particle sizes of the as-prepared NPs were found to be ~20–70 nm. As-prepared hydrated and sintered CoF2 NPs were characterized by Energy-dispersive X-ray spectroscopy, Fourier-transform infrared spectroscopy, Scanning electron microscopy, UV–Vis spectroscopy, thermogravimetric analysis, and X-ray diffraction. Further, cyclic voltammetry has been used to measure the electrochemical performance of as-prepared NPs and the results show that electrochemical performance i.e. reversibility and cyclic stability of the synthesized NPs are highly improved. The sintered CoF2 NPs (~20–50 nm) obtained at ratio 2:2.5 with uniform composition show better electrochemical performances (0.079 mA g−1) as compared to its counterparts. This study reveals that CoF2 NPs has great potential as cathode material in energy storage devices due to its excellent efficiency, low cost, easy synthesis and high yield.Graphical abstractThe hydrated and sintered cobalt fluoride nanoparticles were prepared via simple and environmentally friendly reverse micro-emulsion method.

    • Abstract: Publication date: Available online 23 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Wenhui Kong, Yingmin Wang, Lifeng Wang, Yan Li, Yong Li, Wendong Xue In this paper, the photoluminescence (PL) behavior of reduced graphene quantum dots (rGQDs) was investigated. The rGQDs with different reduced level were obtained by after-reduced electrochemical prepared GQDs using sodium borohydride solution (NaBH4) as reductant. The reduced degree, surface oxygen functional groups, surface defect changes and band gap were detailed investigated through Transmission electron microscopy (TEM), high resolution TEM (HRTEM), Atomic force microscopy (AFM), Ultraviolet–visible spectroscopy (UV–Vis), Photoluminescence excitation (PLE), Fourier transform infrared spectroscopy (FT-IR), Raman spectrum, zeta potential analysis and X-ray photo-electron spectroscopy (XPS). The rGQDs showed higher PL emission and improved quantum yields than GQDs. But as the degree of reduction increased, PL emission decreased. Based on these result, we proposed that the PL change result from the surface hybridization state of GQDs. Our work could help to further understanding of PL behavior and mechanism of GQDs.Graphical abstractUnlabelled Image

  • Effect of synthesis route in the photocatalytic, structural and

    • Abstract: Publication date: Available online 22 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Nicolas Perciani de Moraes, Gabriel Costa Neves, Fernanda Azzoni Torezin, Maria Lucia Caetano Pinto da Silva, Liana Alvares Rodrigues This project aimed to evaluate the synthesis route influence in the structural, morphologic and photocatalytic properties of carbon xerogel/Nb2O5 composites. Infrared spectroscopy and X-ray diffractometry confirm the existence of niobium-based oxides in the composites, whereas the diffuse reflectance and energy dispersive spectroscopy prove the incorporation of the carbon xerogel. The XC-24Nb composite presented the best photocatalytical response, as it presented higher crystallinity, high surface area and superior carbon xerogel incorporation. The XC-24Nb carb was the least effective material, probably due to its considerably inferior surface area. The degradation of methylene blue is controlled by electrons and electron vacancies.Graphical abstractUnlabelled Image
       
  • Two Zn(II)-based metal-organic frameworks for selective detection of
           nitroaromatic explosives and Fe3+ ion
    • Abstract: Publication date: Available online 18 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Hong-Guo Hao, Yu-Chen Wang, Su-Xian Yuan, Di-Ming Chen, Da-Cheng Li, Jian-Min Dou Two new luminescent Zn(II) metal–organic frameworks of [Zn(H2BPTC)](H2O)2 (1) and [Zn4(H2BPTC)2(SO4)2][(CH3)2NH2]4(H2O)4 (2) were constructed using zinc salts and 3,3′,5,5′‑biphenyltetracarboxylic acid (H4BPTC) as building blocks. The resulted MOFs were characterized by IR spectroscopy, thermogravimetric analysis and single crystal X-ray crystallography, and they exhibit different structural topologies: 1 presents a three dimensional (4,4)-connected network with {42.84} topology, while 2 can be described as a (4,6)-connected network with (32.62.72)(34.42.64.75) topology. These differences show that counter-anions play an important role in modulating structural and luminescent properties. Both 1 and 2 possess strong luminescence in suspensions, which can be selectively quenched by some specific nitroaromatics, Fe3+ ion and acetone.Graphical abstractTwo luminescent Zn(II) MOFs have been synthesized through the strategy of anion-induced self-assembly of MOFs. Those two MOFs show different sensitivity and selectivity responses for NACs, Fe(III) ion, and toxic solvents. Comparing with the high sensing selectivity of 1 only towards PA, 2 displays varying degrees of fluorescence quenching for PA, NB, 1,3‑DNB, and 2,6‑DNT. Furthermore, they also exhibit a selectively fluorescent quenching response to Fe3+ ion and acetone.Unlabelled Image

The prepared photocatalyst was fully characterized by various spectroscopic (DRS, Raman and FT-IR) and electron microscopic (TEM and SEM) investigations confirming the chemical formation of the target photocatalyst. The photocatalytic property of TNPC-GPTMS/TiO2 towards the photocatalytic degradation of di-anionic azo dye Acid Black 1 (AB1) was comparatively assessed with the pure TiO2 and GPTMS/TiO2 under visible light irradiation. The results revealed that the TNPC-GPTMS/TiO2 photocatalyst showed much higher photodegradation efficiency than pure TiO2 and GPTMS/TiO2, and importantly 0.004 wt% TNPC-GPTMS/TiO2 shows the highest photocatalytic active under the same condition. In addition, the repetition test demonstrated that the TNPC-GPTMS/TiO2 still maintained high photocatalytic activity over three recycles. Finally, the photocatalytic mechanism was proposed.Graphical abstractThe first example of corrole chemically modified TiO2 photocatalyst was synthesized and its photocatalytic property was investigated by spectroscopic methods.Unlabelled Image

X-ray single crystal analysis shows that compound 1 contains two crystallography independent silver ions, which adopt different coordination modes connecting bpy ligand alternately to form two kinds of metal-organic chains {Agbpy}n. Two parallel {Ag(1)bpy}n chains are linked together via {AsW12O40} linkers to result in a unique sandwich-type dimer chain along a axis. Each Keggin cluster on sandwich chain bonds with six cognate clusters on six adjacent sandwich chains via surrounding six Ag, forming a 2-D layer along c axis. The 2D layer and 1D sandwich chains are intersected to yield a 3D network with 1-D channel. The {Ag(2)bpy}n chains and lattice water reside in the channel and further stabilize the 3-D framework via H-bonding and π-π accumulation.

In the presence of 10 mol% 1·H2O·THF, reductive cleavage SS bond by zinc dust at room temperature led to nucleophilic sulfur anion species, which reacted with alkyl halides to afford unsymmetrical sulfides in good to excellent yield using commercial THF as solvent. Activated chlorides, organic iodides and bromides underwent the reactions efficiently. The possible reaction mechanism is that zinc dust reduces Cp2TiIV(OPf)2 (Pf = SO2C4F9) to generate Cp2TiIIIOPf, which reacts with diaryl disulfides to form Cp2TiIVSAr(OPf) by oxidative addition. Further reaction of Cp2TiIVSAr(OPf) with alkyl halides to afford unsymmetrical sulfides.

  • Trans-kinetic effects in ligand substitution processes of

    • Abstract: Publication date: Available online 5 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Juan H. Mecchia Ortiz, Analia M. Peyrot, Florencia Fagalde, Néstor E. Katz A concerted mechanism is disclosed when studying trans-kinetic effects in substitution process of complexes of formula [Ru(trpy)(4,4′-(X)2-bpy)(H2O)]2+, with trpy = 2,2′:6′,2″-terpyridine, bpy = 2,2′-bipyridine and X = H, CH3, OCH3, NH2 and N(CH3)2. The second order rate constants k2 for substitution of water by acetonitrile increase with increasing donor ability of the X group. The correlation between ln k2 and Hammett substituent constants σp of X gives a slope of near 1, indicating high sensitivity of the kinetic parameters for water replacement to the donor ability of the para-substituent attached to a bipyridine trans- to the water ligand and considerably separated from it. Besides, the activation enthalpies decrease with increasing pKa values of the 4,4′-(X)2-bpy ligands and the activation entropies have negative values almost one order of magnitude higher than those reported before in similar processes. These data indicate a concerted ligand interchange mechanism, infrequently found in substitution reactions of octahedral complexes which can be explained by the fact that H-bonds between the leaving ligand (H2O) and the entering ligand (CH3CN) will favor an intermediate transition state of increased order respect to the initial state. These results are pertinent for finding the best candidates in the quantitative detection of CH3CN, an important contaminant in radiopharmaceuticals used in PET (positron emission tomography) studies.Graphical abstractUnlabelled Image

Cavalcante In this communications, we report the synthesis of nickel tungstate (NiWO4) nanocrystals by controlled co-precipitation at 95 °C for 2 h, followed by heat treatment at 600 °C for 2 h. The structure of the NiWO4 nanocrystals was characterized using X-ray diffraction (XRD) and Rietveld refinement analysis. Field emission-scanning electron microscopy (FE-SEM) was employed to observe the shape, average size and propose a growth mechanism for the synthesized NiWO4 nanocrystals. The optical behavior was investigated by ultraviolet–visible (UV–Vis) spectroscopy and first-principles quantum mechanical calculations based on the density functional theory at the B3LYP level to obtain their electronic band structure and density of states. We investigated the sonophotocatalytic (SPC) properties of the remazol brilliant violet 5R (RBV5R) anionic dye for degradation using a violet light emitting diode of power 10 W. The XRD patterns indicate that the NiWO4 nanocrystals heat-treated at 600 °C for 2 h have a wolframite-type monoclinic structure. The FE-SEM images showed the presence of irregular sphere-like crystals formed by self-assembly of several NiWO4 nanocrystals. The experimental optical band gap energy (Egap(exp)) was found to be 2.77 eV using UV–Vis spectroscopy and theoretical calculations indicate an indirect band gap with Egap 3.91 eV, which the (O 2p orbitals) are predominant in the valence band and the (W 5d orbitals) in the conduction band and inhomogeneous electronic distribution into the lattice with the electron density map. We demonstrate for the first time that SPC activity can be enhanced after 120 min by approximately 32% for the degradation of the RBV5R anionic dye by using a NiWO4 nanocatalyst.Graphical abstractUnlabelled Image

Sigoli In this work, we synthesized the {tris(thenoyltrifluoroacetone)pyrazino[2,3-f][1,10]phenanthroline}europium (III) complex and studied its thermal emission quenching. The crystal structure of the [Eu(tta)3(pyphen)] complex show that the europium (III) ion occupies a distorted D4d symmetry of a square antiprism site. The complex shows an absolute emission quantum yield of 31%. The temperature dependence of the photophysical properties of the complex was evaluated and indicates that the complex has potential to be applied as a lifetime based luminescent thermometer. The quenching of the luminescence as a function of temperature occurs due the energy back-transfer from the emitter state to the ligand centered triplet state. The temperature induced blue-shift in the 5D0 → 7F0 transition band indicates the presence of the electron-phonon coupling in this complex.Graphical abstractUnlabelled Image
       
  • Conducting polymer nanocomposite based temperature sensors: A review
    • Abstract: Publication date: Available online 1 October 2018Source: Inorganic Chemistry CommunicationsAuthor(s): R. Megha, Farida A. Ali, Y.T. Ravikiran, C.H.V.V. Ramana, A.B.V. Kiran Kumar, D.K. Mishra, S.C. Vijayakumari, D. Kim The absolute necessary for measuring temperature with large accuracy and with a wide range in various industrial sectors increases the need for researcher to choose a suitable material, which is useful especially in bio-medical applications, food packaging and air conditioning system. A slight deviation of temperature creates a lot of problems which cannot be controlled rapidly. Hence, the temperature sensor needs to have the properties of high sensitivity, fast response, low cost, high volume production, and high reliability. Considering the essentialities of the temperature measurement almost in all types of industrial sectors, the sensing materials used for fabricating the sensors should have flexibility for both temperature and pressure sensing ability. In this aspect, conducting polymers have an efficient candidate for temperature sensor. As the conducting polymers are fabricated by the incorporation of conducting filler in polymers, the resistivity of such materials is very sensitive to temperature for which response to the signal very fast. The high accuracy measurement as well as wide measurement scale can only be achieved by conducting polymer based sensors which are more stable at high temperature. However, the sensitivity and selectivity of nanostructure conducting polymer-based sensors still needs a lot of enhancement. In the present review, fabrication of conducting polymers and their importance as temperature sensors have been discussed.Graphical abstractUnlabelled Image

Complex Ru(dpphen)32+ displayed a weak emission at 613 nm in CH3CN while exciting at its MLCT band (464 nm). However, upon response with incremental addition of poor and viscous solvents into the CH3CN solution of Ru(dpphen)32+, the emission intensity drastically increased due to the formation of nanoaggregates. Restricted intramolecular rotation (RIR) of peripheral phenyl rings attached to the bathophenanthroline ligands in Ru(dpphen)32+ complex is responsible for this unique phenomenon, thereby stimulates the emission intensity. The formation of these nanoaggregates was confirmed by TEM studies.Graphical abstractNotable aggregation induced emission enhancement (AIEE) found in ruthenium(II) is attached with bathophenanthroline ligand, upon response with poor and viscous solvents that are confirmed by the enhancement of luminescence intensity, quantum yield and the formation of nanoaggregates by TEM.Unlabelled Image

           Er3+-doped LnP5O14 (Ln = La, Gd) ultraphosphates
    • Abstract: Publication date: Available online 21 September 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Aïcha Mbarek Er3+-doped LnP5O14 (Ln = La, Gd) ultraphosphates were synthesized via solid state reaction. The phase purity and the structure of samples were characterized by the X-ray powder diffraction (XRD) and the Fourier transform infrared spectroscopy (FTIR). The optical properties were investigated by analysis of the photoluminescence emission spectra recorded in 430–900 nm and 1450–1600 nm wavelength range at room temperature. Upon visible excitation, the Ln1-xP5O14:xEr3+ (Ln = La, Gd; x = 1–5%) phosphors exhibit bright green emission bands, corresponding to transitions from the 2H11/2 and 4S3/2 erbium levels to the 4I15/2 ground state and week red luminescence related to the 4F9/2 → 4I15/2 transition. A strong luminescence at 1.53 nm in the infrared (IR) region due to 4I13/2 → 4I15/2 transition has been observed in Ln0.95P5O14:0.05Er3+ (Ln = La, Gd) phosphors under the excitation by 488 nm laser light. The experimental results suggest that Er3+ activated ultraphosphates hosts are useful for solid-state lasers applications.Graphical abstractEr3+-doped LnP5O14 (Ln = La, Gd) ultraphosphates have been synthesized via solid state reaction.

  • Preparing BiOI photocatalyst for degradation of methyl blue in wastewater
    • Abstract: Publication date: Available online 18 September 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Jingnan Zhang, Zhizhong Chen, Yunyi Qiu, Mingyang Li, Hao Yang, Yongchao Huang, Jian Chen Photocatalytic oxidation on semiconductors is a green and friendly route to deal with environmental issues. Herein, a novel C/BiOIdefect photocatalyst was prepared by one-step hydrothermal method, and this nanocomposite exhibited excellent photocatalytic degradation performance under visible light irradiation. The substantially increased visible light absorption and separation of photoinduced carriers were attributed to the high photocatalytic performance. Moreover, the C/BiOIdefect also shows outstanding adsorption capacity and photochemical stability, which are also extremely important for practical application.Graphical abstractUnlabelled Image
       
  • Protonation-induced ligand distortion of spin-crossover complexes
    • Abstract: Publication date: Available online 5 September 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Rui Zhang, Dan-Li Hong, Xiao-Tong He, Fang-Hui Chen, Jia Jiao, Xiao-Qing Zhao, Xin Li, Yang-Hui Luo, Bai-Wang Sun A new complex [Fe(CN)2(bipy-NH2)2] (2, bipy-NH2 = 4, 4′-diamino-2, 2′-bipyridine), which was designed through ligand exchange strategy, has been prepared and characterized. The magnetism properties of 2 have been tuned through protonate the amino groups on bipy-NH2 ligand with HCl in stoichiometric ratio 2:HCl below 1:1. Further increase the ratio exceed 1:1 has induced the distortion of the bipy-ammonium moieties in bipy-NH32+ cation, with the dihedral angle involving the mean plane change from 0° to 37°. This distortion, on the one hand, responsible for the decomposition of 2, on the other hand, take charge the break of the precursor complex 1 ([Fe(H2Bpz2)2(bipy-NH2)]) (pz = pyrazolyl) upon protonation.Graphical abstractTuning the magnetism properties of a new complex [Fe(CN)2(bipy-NH2)2] (2) through protonation of the ligand bipy-NH2 with HCl have been investigated with stoichiometric ratio of 2:HCl below 1:1. While once the ratio larger than 1:1, ligand bipy-NH2 has distorted with the mean plane of bipy-ammonium moieties to form a dihedral angle large to be 37°.Unlabelled Image
       
  • Synthesis, spectroscopy and singlet oxygen quantum yield of a
           non-aggregating hexadecamethyl-substituted phthalocyanine silicon(IV)
           derivative
    • Abstract: Publication date: Available online 25 July 2018Source: Inorganic Chemistry CommunicationsAuthor(s): Malcolm Alan Bartlett, Kerstin Mark, Jörg Sundermeyer A rigid hexadecamethyl substituted phthalocyanine (Pc*) silicon(IV) dichloride was synthesized by template cyclization of corresponding 1,3-diiminoisoindoline derivative with SiCl4. Attempts to prepare the same compound by insertion of HSiCl3 into preformed H2Pc* in the presence of bases were unsuccessful. Exchange of the axial chloride ligands with trimethylsiloxy groups made the molecular complex Pc*Si(OTMS)2 very soluble and non-aggregating, as shown by UV–Vis experiments. The effect of such peripheral alkyl substitution on the singlet oxygen quantum yield of the Pc*Si(OTMS)2 complex was determined and found to be 0.28; significantly lower than that for unsubstituted parent PcSi(OTMS)2. The merit of improving solubility over reduced singlet oxygen quantum yields is discussed.Graphical abstractUnlabelled Image
