摘　　要：用化学氧化法 ,以三氯化铁作催化剂、硝基苯作溶剂 ,合成了蓝色电致发光聚合物—二辛氧基聚对苯 ( DOO- PPP) ,重点研究了反应条件对分子量和反应产率的影响 ,并用多种手段对产物进行了表征 .其在空气和 N2 气中的热失重行为基本一致 ,在氯仿溶液中的光致发光波长在4 2 6nm.A blue electroluminescent polymer dioctyloxyl substituted polyparaphenylene(DOO-PPP) was synthesized in nitrobenzene via a chemical oxidative route using FeCl_3 as catalyst. The effects of FeCl_3 amount, temperature, reaction time and monomer concentration on the yield and moleclar weight of DOO-PPP were investigated. The polymer exhibited analogical thermogravimetric behavior both in air and N_2, the peak wavelength of its photoluminescence spectrum in CHCl_3 was at 426 nm.
