conjugation that underwent facile electrochemical polymerization to form stable electroactive polymer. We extended the conjugation of the monomers in comparison to the carbazole and large decrease were observed in the oxidation potential at which polymerization occurs. To lower the oxidation potential of the monomer and control the optical and electronic properties of the polycarbazole, we attached
在这里,我们报告制备3,6-双(苯甲酰基)-N-癸基咔唑,由于扩展的共轭反应,容易进行电化学聚合反应形成稳定的电活性聚合物,因此具有较低的氧化电位。与咔唑相比,我们扩展了单体的共轭作用,并且观察到发生聚合反应时的氧化电位大大降低。为了降低单体的氧化电位并控制聚咔唑的光学和电子性质,我们在N-取代咔唑的3和6位上连接了噻吩,联噻吩和3,4-乙撑二氧噻吩(EDOT)。通过电子顺磁共振(EPR)和UV-Vis-NIR光谱电化学对单体及其聚合物进行了比较,得出了令人感兴趣的特性。
