Yildiz, Burak;Arslan, Baris Seckin;Guzel, Emre;Nebioglu, Mehmet;Menges, Nurettin;Sisman, Ilkay;Kasim Sener, M. research published 《 Non-aggregating zinc phthalocyanine sensitizer with bulky diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group for coadsorbent-free dye-sensitized solar cells》, the research content is summarized as follows. A novel unsym. zinc phthalocyanine complex (PCA-ZnPc-3) containing six 2,6-diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group has been synthesized and used as a sensitizer for dye-sensitized solar cells (DSSCs). The optical, electrochem. and photovoltaic characteristics were evaluated and compared with the dyes containing the same anchoring group and tert-Bu (PCA-ZnPc-1) or hexylsulfanyl (PCA-ZnPc-2) donor groups, developed by our group. The DSSC with PCA-ZnPc-3 exhibited a higher power conversion efficiency (PCE) of 2.04% as compared to that of PCA-ZnPc-1 (PCE = 1.74%) and PCA-ZnPc-2 (PCE = 1.89%). This enhancement in efficiency may be ascribed to the less dye aggregation and appropriate dye coverage. These results suggest that the incorporation of 2,6-diphenylphenoxy into pyrazole-3-carboxylic acid-based zinc phthalocyanine sensitizers can improve photovoltaic performance of DSSCs.

A.;Kucernak, Anthony R.;Jelfs, Kim E.;McKeown, Neil B.;Song, Qilei research published 《 Development of efficient aqueous organic redox flow batteries using ion-sieving sulfonated polymer membranes》, the research content is summarized as follows. Redox flow batteries using aqueous organic-based electrolytes are promising candidates for developing cost-effective grid-scale energy storage devices. However, a significant drawback of these batteries is the cross-mixing of active species through the membrane, which causes battery performance degradation To overcome this issue, here we report size-selective ion-exchange membranes prepared by sulfonation of a spirobifluorene-based microporous polymer and demonstrate their efficient ion sieving functions in flow batteries. The spirobifluorene unit allows control over the degree of sulfonation to optimize the transport of cations, while the microporous structure inhibits the crossover of organic mols. via mol. sieving. Furthermore, the enhanced membrane selectivity mitigates the crossover-induced capacity decay while maintaining good ionic conductivity for aqueous electrolyte solution at pH 9, where the redox-active organic mols. show long-term stability. We also prove the boosting effect of the membranes on the energy efficiency and peak power d. of the aqueous redox flow battery, which shows stable operation for about 120 h (i.e., 2100 charge-discharge cycles at 100 mA cm^-2) in a laboratory-scale cell.

In order to prepare aromatic nitrile-based resins with improved curing reactivity, thermal and thermomech. properties, and to clarify the difference in curing activity between dicyanoimidazole and phthalonitrile groups, a novel class of autocatalytic aromatic nitrile-based resins named PNDCI which contains both dicyanoimidazole (DCI) and phthalonitrile (PN) groups were designed and synthesized. A method for evaluating the reactivity of nitrile groups using the absorption wavenumber of FTIR was proposed. PNDCI monomers have demonstrated higher activity for self-promoted curing reactions than benzimidazole-containing phthalonitrile monomers (BIPN). The introduction of DCI can change the curing pathway of PN and inhibit the formation of phthalocyanine ring which is an important cured product of PN resins. The data of TGA, DMA, etc. revealed that the cured products of PNDCIs showed outstanding thermal stability, long-term thermo-oxidative stability at high temperatures (425°C) and thermal mech. properties, which is favorable for the preparation of high temperature resistant resins.

Yang, Liu;Chen, Suyuan;Yi, Dong;Chen, Qingxin;Zhang, Jie;Xie, Yusheng;Sun, Hongyan research published 《 Synthesis and fluorescence properties of red-to-near-infrared-emitting push-pull dyes based on benzodioxazole scaffolds》, the research content is summarized as follows. Fluorescence imaging with high temporal and spatial resolution has emerged as one of the most promising techniques to monitor biomols. and biol. processes in living systems. Among many kinds of small mol. fluorescent dyes, 2,1,3-benzoxadiazole (BD) derivatives have been widely applied in many chem. and biol. applications due to their excellent photophys. properties. However, only a limited number of BD dyes with long emission wavelengths were reported. Herein, we have reported a new class of red-to near-IR-emitting small mol. dyes 2a-3a based on benzodioxazole scaffolds, which are named VBDfluors. To bathochromically shift both absorption and emission, the conjugation system was extended by introducing electron-withdrawing group-substituted vinyl groups at position 7 via a Knoevenagel condensation reaction. The basic photophys. properties of VBDfluors were detected and summarized. The VBDfluors display excellent photophys. properties, including emission in the red-to-NIR region, large Stokes shifts, good stability/photostability and cell permeability. The geometry of the mols. was optimized by d. functional theory (DFT) and time-dependent DFT (TDDFT) methods. Bioimaging results indicated that 2a and 3a exhibited excellent cell permeability and could be utilized for visualization of lipid droplets in living cells.

Yang, Dongfeng;Wang, Chengyi;Wang, Yu;Liu, Guohua;Cheng, Tanyu;Liu, Rui research published 《 One-pot enantioselective construction of 3,4-dihydro-2H-1,4-oxazines over Ru/Au relay catalysis and its mechanistic serendipity》, the research content is summarized as follows. The preparation of enantiomerically pure 1,4-oxazines remains a continuous challenge in synthetic chem. because of their potential application in the total synthesis of morpholines. Herein, a one-pot asym. transfer hydrogenation/cyclization enantio-relay process catalyzed by Ru and Au bimetallic catalysts was developed. This enantio-relay process firstly allows the asym. transfer hydrogenation of alkynones to form chiral alkynols in the presence of (S,S)-mesityleneRuClTsDPEN (TsDPEN = N-(p-toluenesulfonyl)-1,2-diphenylethylenediamine) and then the chiral alkynols could be converted into 3,4-dihydro-2H-1,4-oxazines in moderate to good yields with excellent enantioselectivity retention accompanied by AuCl(PPhz₃)/AgNTf₂ and HCOOH. A series of sulfonamide-tethered alkynones were well tolerated in this process. Mechanistic studies indicated that the alkynols formed in the first step were initially transformed into a methylenemorpholine intermediate when AuCl(PPh₃)/AgNTf₂ and HCOOH were added, which can be further isomerized into chiral 3,4-dihydro-2H-1,4-oxazines with the addition of a second HCOOH. This protocol offers not only a practical method to access 3,4-dihydro-2H-1,4-oxazines from alkynones in an enantioselective version, but also enriches the arsenal of gold chem. from a mechanistic point of view.
