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1H NMR 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.

Abstract: 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)64- on the cationic PPV derivative was studied, and a downward Stern-Volmer curve was found.

Key words: Conjugated polyelectrolytes, Quenching effect, Poly(p-phenylenevinylene)
