基于四苯乙烯衍生物的合成、表征及光学性能研究

Synthsis,Characterization and Optic Property Based on Tetraphenylethylene Derivative

以4,4-二羟基二苯甲酮和三甲基氯硅烷为原料,在四氯化钛和锌粉的催化作用下,合成得到了一种新型的四苯乙烯衍生物,通过质谱、元素分析、核磁氢谱对该配合物进行了充分表征,并对该化合物进行了荧光性能的研究.结果表明,该化合物在四氢呋喃溶液中荧光非常微弱,当四氢呋喃与惰性溶剂水按照9:1和1:9比例配比时,荧光发射峰急速增强,且发生了红移现象.这一点充分说明,由于惰性溶剂水的加入,促使化合物发生了聚集现象,聚集效应诱导了该化合物的荧光强度(AIE效应),为以后的固体材料的研究奠定了基础.

A novel tetraphenylethylene compound was obtained with the raw material of 4,4＇- dihydroxybenzophenone and trimethylchlorosilane with presence of titanium tetraehloride and zinc as the catalysis. The compound has been fully characterized by mass spectrometry, elemental analysis, ^1H NMR spectrum. The fluorescence properties of the compound were also studied. The result shows that the fluorescence intensity of title compound in solvent is very weak, and when the inert solvent water was added in the THF solvent, the fluorescence intensity will be enhanced greatly. So we made up the solvent of water： THF as the ratio of 9 ： 1 and 1：9 and the fluorescence emission peak rapidly increased, and red shift was happened. This fully shows that, due to the inert solvent, water is added, prompting the compound occurred aggregation, aggregation effect induced fluorescence intensity （ AIE effects） of the compound, and laid a solid foundation for future research materials.
