摘 要这些年来,一种新型的具有聚集诱导发光(aggregation-induced emission, AIE)效应的有机荧光分子已经引起了科学界的广泛关注。其中,四苯基乙烯(Tetraphenylethylene, TPE)是一种具有简单的分子结构但表现出极好的聚集诱导发光效应的有机荧光分子,如果使用TPE作为基本构建模块,在此基础上嫁接羧酸、酯、酰胺等分子结构,可以得到多种高效的固态发光有机配体。四苯基乙烯及其衍生物因其具有发光性能优良、易功能化、合成简便、AIE 效应明显等优点得到很多研究者的青睐。TPE及其衍生物作为刚性有机配体构建的发光金属有机骨架,在传感、催化、检测等领域已经显示了非常具有前景的应用价值。我们主要研究了基于四苯基乙烯结构构造的两个具有AIE效应的配体,分别为酰胺二酚四苯乙烯(H8L1)和β-二酮四苯乙烯(TAPPE),这两个配体都具有聚集诱导发光效应。在一定条件下,酰胺二酚四苯乙烯(H8L1)与Ga(III)成功合成具有荧光效应的金属有机配合物。我们还发现溶剂分子、反应物的浓度、反应的温度以及反应物的配比等条件都会影响配合物的质量。89831
Abstract:Over the years, a new type of organic fluorescence molecules with aggregation-induced emission (AIE) has attracted wide attention from the scientific community。 Among them, Tetraphenylethylene (TPE) is an organic fluorescent molecule with simple molecular structure but showing excellent aggregation-induced luminescence effect。 If TPE is used as the basic building block, grafted carboxylic acid, Ester, amide and other molecular structure, can be a variety of efficient solid-state luminescent organic ligands。 Tetraphenyl ethylene and its derivatives are favored by many researchers because of their excellent luminescent properties, easy functionalization, simple synthesis, obvious AIE effect。 TPE and its derivatives as a rigid organic ligand to build the organic metal matrix, in the sensor, catalysis, detection and other fields has shown a very promising application value。 We mainly studied the ligand amide diol tetramethylene and β-diketyltetramethylene (TATTPE) based on the structure of tetrastyrene, both of which have aggregation-induced luminescence effects。 Under certain conditions, amide diol tetrastyrene and Ga (III) successfully synthesized with fluorescent effect of metal organic complexes。 We also found that the solvent molecules, the concentration of reactants, the temperature of the reaction, and the ratio of the reactants would affect the mass of the complex。
