摘　　要：利用斯蒂尔偶联反应合成了两种有机共轭单体,通过电化学方法聚合成导电聚合物,并对其进行了结构表征和电化学性能研究.核磁共振1H 谱和13C谱验证了单体与理论结构一致,红外测试验证了电化学聚合位点为噻吩的α位.在0-1.2V 电压范围内,两种聚合物膜都表现出电致变色特性.相比于聚合物P1,结合力更强的聚合物P2的电化学和热稳定性更优.结论表明,苯并硒二唑类聚合物在电致变色领域是一种有前景的材料,单体结构差异对聚合物性能有很大影响.Two organic conjugated monomers were prepared via the Stille coupling reaction,conductive polymers were prepared by electrochemical method,structure and photoelectric properties of monomers and polymers were investigated.1 H NMR and 13 C NMR of monomers were consistent with the theory,FT-IR showed electrochemical polymeric site wasα-position of thiophene.When applied voltage was from 0to 1.2V,both of the polymer films showed electrochromic performances.Compared with P1,P2 had better electrochemical stability and thermal stability due to the stronger force effect by repeated cyclic voltammograms and TGA.The above conclusion proved that the P2 based on benzoselenadiazole was a more promising material in the electrochemical field,meanwhile,it showed that the monomer structure had greatly impact on the performance of polymer.
