JOURNAL FREE ACCESSDespite the well-studied redox and Lewis acidic attributes of organotellurium compounds, such properties are underutilized in their coordination chemistry. This review aims to highlight recent developments in the coordination chemistry of tellurium ligands supported by auxiliary donor groups, which facilitate both coordination and redox non-innocent behavior at the tellurium center by enforcing the Te–M interaction.View full abstract

Supplementary materialWe observed pressure effects on the rate of thermal fading of colored chromene 1 photochemically generated from 2 in ionic liquids. The reaction rates were retarded with increasing pressure in [C4-mim][CS], [bzl-mim][Tf2N], and [mnp-mim][Tf2N], whereas the reaction rate increased with pressures in [C4-mim][Tf2N]. These pressure-induced retardations, so-called dynamic solvent effects, result from the slow thermal fluctuations of solvents.View full abstract -

Supplementary materialA new biradical, 5-methoxy-1,3-phenylene bis(tert-butyl nitroxide), was synthesized and structurally characterized. The magnetic susceptibility measurement indicates that each molecule behaved as an S = 1 species even at 300 K and that ferromagnetic chains were formed with the intermolecular coupling constant of 2J/kB = +2.52(5) K. The methoxy oxygen atom plays an important role in crystal engineering and magnetic coupling.View full abstract -

Supplementary material9H-9-Silafluorene with two alkoxy groups underwent dehydrocoupling in the presence of [Pt(dmpe)2] (dmpe: 1,2-bis(dimethylphosphino)ethane) to produce tetrasilaplatinacyclopentanes having four silafluorenylene units. Ligand exchange of the persilylated platinacycles with non-substituted silafluorene released tetrasilane dihydrides with two pairs of π-stacked biphenylene units. [Ni(dmpe)2] catalyzes the dehydrogenative polycondensation of 2,7-dibutoxy-9H-9-silafluorene to produce the poly(1,1-silafluorene).View full abstract -

Supplementary materialIn recent years, waste rubber in the form of scrap tires has increased significantly in amount, and its disposal has become an important issue. We focused our attention on lipid peroxidation, which has a low environmental burden. Shredded vulcanized rubber samples were dipped in a small quantity of solvent, and stirred for 48 h. Significant reductions in molecular weights of the rubber samples were confirmed. From the structural analysis of the degradation product, formation of hydroxy and carbonyl groups, a decrease in β-position methylene protons and olefin protons, and a reduction in carbon–carbon double bonds were confirmed. Therefore, auto-oxidation is suggested as the reaction that reduced the molecular weight. The reaction mechanism involved lipid peroxidation by radical species that extracts hydrogen atoms. It is presumed that the polymer radicals generated undergo β-scission reactions caused by auto-oxidation, resulting in reduction of the diene polymer molecular weight.View full abstract -

Supplementary materialDespite the importance of copper-catalyzed reactions in preparing functional polymeric materials, trace amounts of copper remaining in the final product is often an issue, especially for polymers having high affinity towards copper ions. We developed a new copper removal method that dissociates strongly coordinated copper impurities form the polymer using diethyldithiocarbamate (DTC) as a complexing ligand followed by size exclusion chromatography to separate the copper-free polymer from the copper/DTC complex. This method could be applied to remove trace amounts of copper from a wide variety of polymers prepared by copper-catalyzed reactions.View full abstract -

Supplementary materialPyrenyl-substituted 1,3-butadienes bearing alkyl and aryl groups have been synthesized by palladium-catalyzed addition of 2-borylpyrene to internal alkynes. On UV irradiation, 1-pyrenylbutadienes undergo photochromism in solution. In the solid state, 1-pyrenyl-1,2,3,4-tetraaryl-1,3-butadiene exhibits red-shifted and broad emission as compared with the alkylated butadiene. The charge-carrier mobility of 1-pyrenyl-1,2,3,4-tetraalkyl-1,3-butadiene is higher than that of the arylated butadiene.View full abstract -

Supplementary materialMesoporous poly(melamine–formaldehyde) (mPMF) is a versatile solid adsorbent owing to its mesoporous network structure and rich nitrogen-containing functional groups. Herein, a facile method was reported for the first time to make mPMF by polycondensation between melamine and formaldehyde in ethylene glycol at 170 °C for 48 h. The resulting mPMF possesses high nitrogen content (50.28%), a mesoporous fibrous framework, a uniform pore size (ca. 12.6 nm), a high BET surface area (334.5 m2 g−1), a large pore volume (1.06 cm3 g−1), and good thermal stability (Tdec > 400 °C). Its application in wastewater treatment was demonstrated by the adsorption of various water contaminants.View full abstract -

Supplementary materialElectrophilic additions of HF and HCl to a series of asymmetric alkenes have been investigated by the ab initio and ABEEM-σπ model in the gas phase. In the ABEEM-σπ model, the site activation method is studied by discussing changes in the local softness, Fukui function, and global softness from reactants to transition states. Compared with the substituent Hammett constants σp, most negative-valued point of molecular electrostatic potentials in the π-region (Vmin values), and KED that is a characteristic mark of the electron density at the π-region in the initial-state of the alkenes obtained by molecular face model, indicates that the ABEEM-σπ model could well describe the regioselectivity rule in terms of the site activation method.View full abstract -

Advance online publication: January 23, 2016JOURNAL RESTRICTED ACCESSThe films of a dicyanostilbene derivative (DBDCS) cast from an alcoholic solution show aggregation-induced emission enhancement by UV light irradiation and a fluorescence color change from green to blue upon heating. The former can be attributed to the planarization by rotational motion around the olefin moieties due to elevation in the local temperature via the excited state by UV irradiation. The latter originates from the phase transformation of DBDCS with cooperative alcoholic desorption and molecular reorganization.View full abstract -

Supplementary materialA novel soluble well-defined ladder polysiloxane bridged by imido linkages having a high molecular weight was successfully synthesized via the corresponding supramolecular intermediate and was fabricated to a very flexible self-standing membrane. The membrane showed a better oxygen permselectivity than conventional linear polyorganosiloxanes. We directly observed the effect of the regular molecular-sized pores formed by the ladder structure on the oxygen permselectivity for the first time. This is the first report on gas permeability thorough a well-characterized ladder polymer.View full abstract -

Supplementary materialA mixture of triphenylphosphine and zeolite Y was thermally treated in an autoclave (423 K, 24 h), resulting in the inclusion of PPh3 in the supercage of zeolite Y, up to 21 wt % (1.5 PPh3 molecules per supercage). PdCl2 was introduced to the PPh3-treated zeolite Y to fabricate a Pd complex in the supercage, and a coupling reaction was performed over the obtained complex. The turnover frequency increased with increased PPh3 loading, suggesting that the [PdCl2(PPh3)2] complex included in the supercage could be the active species.View full abstract -

Supplementary materialElectrochemical synthesis of new phenothiazine derivatives was carried out via electrochemical oxidation of hydroquinones (1a and 1b) in water/ethanol (90/10) solution containing 0.15 mol L−1 phosphate buffer (pH 6.0) in the presence of 2-aminothiophenol (3) using cyclic voltammetry (CV) and controlled potential coulometry (CPC) methods. The results show that electrochemically generated p-benzoquinones participated in the 1,4-Michael addition reaction with 3 via an ECEC mechanism to form phenothiazine derivatives 6a and 6b in good yields and high purity using a facile, one-pot, clean, and non-catalyst method by three carbon electrodes in an undivided cell.View full abstract -

Supplementary materialWe examined photoresponsive ionic liquids containing an azobenzene moiety. Ionic liquids with a p,p′-azobenzene or o,p′-tetrafluoroazobenzene moiety exhibit a reversible solid-to-liquid phase transition induced by photo- and thermal-stimulation. o,p′-Azobenzene, which exists as an ionic liquid with a bent structure, is in a liquid state even as a trans-isomer. Such photoresponsive ionic liquids may be useful as novel functional materials, such as in optical sensors.View full abstract -

Supplementary materialA Co(III) complex possessing selective nitric oxide (NO) capturing ability was immobilized onto a bulky phosphonium type ionic liquid-modified Au electrode, IL/Au, (Co@IL/Au), which was confirmed by several physicochemical methods, such as IR-RAS and electrochemical measurements. The Co@IL/Au exhibited a significant change in its chemical properties after reaction with NO, indicating that it captures the NO molecule. Furthermore, it might be able to determine the quantity of NO concentration in an aqueous solution only in a low concentration range of NO, from 0 to 160 ppb.View full abstract -

Supplementary materialRenewable resources-based homo- and copolyesters were prepared from novel vanillin-based Schiff base and biobased cinnamic acid derivatives by transesterification. Chemical structures of the Schiff base and resulting polyesters were confirmed by FT-IR, 1H NMR, and 13C NMR. Glass-transition temperatures of polymers were determined by DSC and showed over 100 °C. Photoluminescence properties were investigated for the Schiff base and polyesters. For polymers, broader emission spectra were observed compared with monomers, which probably originated from intramolecular charge transfer in each monomeric unit.View full abstract -

Supplementary materialIn this study, two flower-like δ-MnO2 microflowers and α-MnO2 nanotubes were synthesized by a simple hydrothermal route. The catalytic activities of three samples for resorcinol degradation and oxidation of formaldehyde (HCHO) were evaluated, and the effects of crystal phase and morphologies on the activities of the three MnO2 samples were investigated. The activities of the catalysts decreased in the order of α-MnO2 nanotubes > two of δ-MnO2 microflowers and α-MnO2 nanotubes degraded resorcinol in 30 min at resorcinol concentration 20 mg L−1 and achieved complete HCHO conversion at 80 °C. It was found that the crystal phase and morphologies of the MnO2 samples mainly predominated the catalytic activities.View full abstract -
