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 , respectively . the fluorescence of the polymer solution with different concentration was investigated using variable excitation wavelength from uv to visible region . the relation between fluorescence and polymer structure was studied . the results showed that the molecular chain structure has great influence on fluorescence of the polymers . the emitting peak wavelength of fluorescence for the polymer of high stereoregularity is independent of solution concentration and excitation wavelength . the emitting peak wavelength of fluorescence for the polymer with disordered molecular chain arrangement varies with changing the solution concentration and excitation wavelength , and different emission sites in molecular chains and low emitting yield are shown . the measurement and analysis of fluorescence spectroscopy of polyphenylacetylenes may provide some useful information to judge the molecular chain arrangement in some conjugated polymers 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
