带不同推电子基团二聚苯撑乙烯的电子结构与发光性能 总被引:1,自引:0,他引:1
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. 相似文献

The syntheses of a series of oligo (phenylene vinylenes) (OPVs) were described. The extended it-chains were built up by sequences of Wittig reactions. Their electronic structures were systematically studied with absorption spectra, photo-luminescent spectra. The influences of the effective conjugation length on the performance of the light emitting devices were investigated. 相似文献
