【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1 H谱和13 C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。
[Abstract]:Two kinds of organic conjugated monomers were synthesized by Steele coupling reaction and polymerized into conductive polymers by electrochemical method, and their structure and electrochemical properties were studied. Nuclear magnetic resonance 1H spectra and 13 C spectra confirmed that the monomer was consistent with the theoretical structure, and the electrochemical polymerization site was confirmed to be the 伪 site of thiophene by infrared spectroscopy. In the voltage range of 0 鈮，
