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 A series of diphenylene ethers with different electron-withdrawing substituents were synthesized using the Wittig route. Their electronic structures were determined by UV-Vis spectroscopy and cyclic voltammetry. The electronic energy levels of the oligomers were modeled using quantum chemistry calculations. The relationship between absorption spectra, emission spectra and the electronic structure of chromophores is discussed
