以3，6-二乙烯-9-癸基咔唑和4，7-二溴-2，1，3-苯并噻二唑(或2，7-二溴荧酮)为原料，通过Heck缩聚反应合成了两种新型的可溶性芳香烃聚合物，其主链上分别含有一个给电子单元和一个接受电子单元。在甲苯溶液中，含苯并噻二唑单元的聚合物表现出强烈的红色光致发光，而含荧酮单元的聚合物则表现出白黄色的光致发光。聚合物具有良好的热稳定性，5wt%的失重温度在430℃以上。电化学测试表明，聚合物在还原条件下是可逆的。
Two new soluble arylenevinylene-based polymers comprising of an electron-donating carbazole unit and an electron-accepting 2,1,3-benzothiadiazole (or fluorenone) unit in the main chain were synthesized by Heck polycondensation between 3,6-divinylene-9-decyl carbazole and 4,7-dibromo-2,1,3-benzothiadiazole (or 2,7-dibromofluorenone). In the toluene solution, a polymer with benzothiadiazole unit showed strong red photoluminescence, whereas the polymer with fluorenone unit showed white–yellow photoluminescence. The polymers had good thermal stability with 5wt% loss temperature of more than 430°C. Electrochemically, the polymers appeared to be reversible under reduction.
