摘　　要：通过Wittig反应合成了新型聚对苯乙烯撑类阳离子共轭聚合物,并进行了相关结构表征和光学性质表征.从1HNMR谱图分析得知,该聚合物具有一定含量的顺式构型.经过季铵化以后得到相应的阳离子共轭聚合物.荧光猝灭行为研究表明,该阳离子共轭聚合物表现出不完全荧光猝灭.A novel poly（p-phenylenevinylene） related copolymer was synthesized by Wittig reaction. The corresponding cationic conjugated polymer was successfully obtained via a post-polymerization approach. On the basis of ^1H NMR spectra, it was found that this phenyl-substituted PPV related copolymer is of 30% cis-vinylic linkage. The quenching effect of Fe （CN）6^4- on the cationic PPV derivative was studied, and a downward Stern-Volmer curve was found.
