Synthesis of (2,5-Dialkoxyl-p-Phenylene Vinylene) Copolymers and Their Photoluminescent and Conductive Properties

采用含氯前聚物路线合成 [2 ,5—二 (甲氧基 )对苯乙炔— CO— 2 ,5—二 (十二烷氧基 )对苯乙炔 ]无规共聚物。用元素分析、凝胶渗透色谱仪、吸收光谱及DSC进行表征。研究了投料比对共聚前聚物组成、收率、分子量及分子量分布的影响 ,并研究共聚物的组成与导电率、溶解性及发光性能的关系。

Poly (2,5 dimethonxy p phenylene vinylene co 2,5 didocyloxy p phenylene vinylene) were synthesized via chlorine precursor route and characterized by elemental analysis,GPC,DSC and absorption spectra. The effect of charging ratio on composition,molecular weight,solubility,conductiity and photoluminescent properties were studied.The relations between copolymers composition and conductivity,luminescence and solubility properties were investigated.
