英文: Abstract: Polyphenylacetylenes were synthesized by [Rn(nbd)Cl]2 and WCl6/Ph4Sn catalyst systems in N2 at room temperature.Polymers with high yield and high molecular weight were obtained.Their structures were characterized by UV,IR,NMR and GPC,respectivel
中文: 文摘:使用有机金属铑、金属钨/四苯基锡催化剂体系聚合苯乙炔,分别获得了高产率和高分子量的聚苯乙炔.使用UV,IR,NMR,GPC等分别对聚合物结构进行了表征.采用不同波长的激发光对聚合物荧光性能进行研究,详细分析了聚合物结构与荧光性能之间的关系.研究结果发现,不同聚合物结构对聚合物荧光性能产生很大影响,规整性高的聚合物,将有较高的发光量子效率;聚合物规整性差,将可能导致多个荧光发光结构点,其荧光强度降低.聚合物荧光光谱研究将对某些共轭聚合物结构的规整性分析提供一些有用的信息.
