摘要：This article summarized the recent advance on the structural design and synthetic strategies of intramolec- ular charge-transfer compounds as well as their potential ap- plications in two-photon absorption chromophores, organic photovoltaics and organic light-emitting diodes.

摘要：Photocatalytic H2 evolution reactions on pristine graphitic carbon nitrides(g-C3N4),as a promising approach for converting solar energy to fuel,are attractive for tackling global energy concerns but still suffer from low *** this article,we report a tractable approach to modifying g-C3N4 with vanadyl phthalocyanine(VOPc/CN)for efficient visible-light-driven hydrogen production.A non-covalent VOPc/CN hybrid photocatalyst formed viaπ-πstacking interactions between the two components,as confirmed by analysis of UV-vis absorption *** VOPc/CN hybrid photocatalyst shows excellent visible-light-driven photocatalytic performance and good *** optimal conditions,the corresponding H2 evolution rate is nearly 6 times higher than that of pure *** role of VOPc in promoting hydrogen evolution activity was to extend the visible light absorption range and prevent the recombination of photoexcited electron-hole pairs *** is expected that this facile modification method could be a new inspiration for the rational design and exploration of g-C3N4-based hybrid systems with strong light absorption and high-efficiency carrier separation.

摘要：Designing of high electrochemical performance organic electrode materials has attracted tremendous attention. Recent investigations revealed that quinone-based polymers along with the stable thioether bonds could achieve a high specific capacity and a good cycling stability simultaneously. In this study, we synthesized a novel ladder-structured polymer poly(2,3-dithiino-1,4- benzoquinone)(PDB) through a simple two-step polymerization. The electrochemical performance indicated that PDB could achieve a high reversible specific capacity of 681 m Ah g-1 with 98.4% capacity retention after 100 cycles. A good rate performance was also achieved with a fast recovery of the capacity after testing at different current densities. Ultra-long cycling performance of PDB was also investigated. The promising results of PDB provided us more confidence to continue searching for high performance polymers through the modification of organic structures.

摘要：磷作为一切生物体的必需元素,参与了包括生命体能量代谢、结构调控、遗传信息传递等在内的必要过程,其重要性不言而喻。然而,在国内基础学科教学过程中,基于酶促反应的调控机制和反应机理被拆分到众多生化专业相关的课程中,并未能得到系统性的剖析与讲解。本文从基础磷酸酯和磷酸酐的化学结构及反应特性入手,分别讨论了生物体中磷酸酯相关的调控酶类,并对最重要的一类磷酸酐——三磷酸腺苷在生物体内的转化关系做了系统性的讲解及分析。作为对磷元素相关的生命化学过程的梳理归纳,希望对化学及生命科学的教学与科研实验设计有所助益。
