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。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 Vis 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.
