摘要: 用Wittig路线合成了一系列带不同推电子取代基的二聚苯撑乙烯,用紫外光谱和循环伏安方法测定其电子结构,并用量子化学计算方法对齐聚物的电子能级进行模拟.讨论了吸收光谱、发射光谱与生色团的电子结构的关系.

关键词: 二聚苯撑乙烯, 电子结构, 发光性能

Abstract: A series of phenylenevinylene dimers with different electron-releasing substituents were synthesized by Wittig reaction. Their electronic structures were characterized with cyclic-voltammetry and UV-V is spectra, their energy levels were calculated with a quantum chemical calculation approach (AM1), the relationship between the photoluminescent property and the electronic structure was systematically discussed.

Key words: Phenylenevinylene dimers, Electronic structure, Photoluminescent property
