二苯甲酸基四苯乙烯配体及配合物的合成及表征

摘要自2001年唐本忠课题研究组发现六苯基噻咯（HPS）这类具有聚集诱导发光（AIE效应）的分子以来，投身于该项目的研究者越来越多。其中四苯基乙烯（Tetraphenylethylene，TPE）作为一种具有简单分子结构但表现出极好的聚集诱导发光效应的发光分子，得到众多科研工作者的青睐。研究者们使用TPE作为基本的构建模块，嫁接羧酸等，延伸出多种高效率的固态发光有机配体。本文就是以4-溴二苯甲酮为原料，在锌粉和四氯化钛的催化作用下，合成得到一种新型的四苯乙烯衍生物—-对二溴四苯乙烯（2Br-TPE）,再进一步与4-甲氧羰基苯硼酸和催化剂作用下合成得到一种四苯乙烯为结构基础的新配体，二苯甲酸基四苯乙烯（H2BCPTPE）,通过核磁氢谱，红外元素分析对该配合物进行了充分表征，并对其进行了荧光性能的研究。后在配合物研究过程中，我们发现在不同溶剂分子中，配体能够以不同的结构以晶体形式析出，这为成功合成具有荧光的金属有机配合物提供了一种新想法新思路。89841

Abstract：Since 2001, Tang's research group has found that there are more and more researchers involved in this project since the discovery of molecules with aggregation-induced luminescence (AIE effect) such as hexaphenyl thiols (HPS) was found by Tang’s reseach group in 2001。 Among them, teraphenylethylene (TPE) is a kind of luminescent molecule with simple molecular structure, but showing excellent aggregation-induced luminescence, which has been greatly favored by researchers。 TPE, as a basic building block, grafted carboxylic acid, etc。, extending a variety of high-efficiency solid-state luminescent organic ligands。 A new type of tetramethylene derivative, 2Br-TPE, was synthesized by the reaction of zinc bromide and titanium tetrachloride with 4-Bromobenzophenone as the starting material, and further reacted with 4-methoxycarbonylbenzene (H2BCPTPE) was synthesized by the reaction of boric acid and catalyst。 The complex was characterized by nuclear magnetic resonance spectroscopy and infrared element analysis。 Conducted a study on the fluorescence properties。 We found that in different solvent molecules, the ligand can be precipitated in different forms of crystals, which provides a new idea for the successful synthesis of fluorescent organic complexes。源Q于W优E尔A论S文R网wwW.yOueRw.com 原文+QQ75201,8766
