通过Wittig反应合成了一种共轭主链上不含大体积苯取代基的阳离子型聚对苯撑乙烯类共聚物。通过核磁共振氢谱、紫外光谱和荧光光谱对其分子结构和光学性质进行了研究。结果表明，聚对苯撑乙烯类共聚物存在不完全猝灭现象，这与含有大体积取代基的阳离子聚对苯撑乙烯类共聚物的猝灭行为一致，可能与共聚物的共轭主链构象和分子间聚集有关。
A cationic poly(p-phenylene vinylene) related copolymer without bulky phenylene substitutents attached to the conjugated backbone was prepared through Wittig reaction. The molecular structure and optical properties were highly investigated through 1H-NMR, UV and PL spectroscopy. The quenching behavior was also investigated, and the results demonstrate that incomplete quenching exists, which is consistent with the cationic poly(p-phenylene vinylene) related copolymer containing bulky phenylene substitutents, probably correlated with the conformation of conjugated backbone and intermolecular aggregation.
