合成方法对导电高分子聚取代PPV性能的影响

采用４种不同方法合成了导电高分子聚（２，５－二甲氧基对苯乙炔）（ＰＰＶ），并对性能进行了研究。实验结果表明，不同合成方法影响前聚物的产率、分子量及其分布、以及微观结构。由４种方法所得导电聚合物的结构也有差别，由此影响产物的光致发光效率、导电率。并对合成方法的适用性进行了比较，筛选出适宜的方法以制备高质量的聚（２，５－二甲氧基对苯乙炔）。

EFFECTS OF SYNTHETIC METHOD ON PROPERTIES OF SUBSTITUTED PPV

Conductive polymers of poly (2,5 dimethoxy p phenylene vinylene) were synthesized by four different methods, and their photoluminescent and conductive properties were studied. The results indicated that different synthetic methods affected the molecular weight, polydispersity index and sturctures of precursor polymer. The photoluminescent efficency and conductivities of poly (2,5 dimethoxy p phenylene vinylene) were also effected by the synthetic methods. The optimum methods was chosen out by comparsion.
