聚（2，7-咔唑）衍生物的合成是因为它们具有比聚（3，6-咔唑）更长的共轭长度和更低的能带隙;然而，关于聚（2，7-咔唑）的电化学合成的研究报道很少。本文合成了一系列N-烷基化-2，7-二（2-呋喃基）咔唑、N-丁基-2，7-二（2-噻吩基）咔唑和N-丁基-2，7-二（2-（3，4-亚乙基二氧噻吩基））咔唑，通过电化学聚合得到聚（2，7-咔唑）衍生物的电活性膜。循环伏安法表明，这些单体具有优异的聚合活性，因为它们的氧化电位较低（
Poly(2,7-carbazole) derivatives have been synthesized because they have more extended conjugation lengths and lower energy bandgaps than poly(3,6-carbazole)s; however, few studies regarding electrochemical synthesis of poly(2,7-carbazole)s have been reported. Here, a series of N-alkylated-2,7-di(2-furyl)carbazoles, N-butyl-2,7-di(2-thienyl)carbazole, and N-butyl-2,7-di(2-(3,4-ethylenedioxthienyl))carbazole, were synthesized to obtain electroactive films of poly(2,7-carbazole) derivatives by electrochemical polymerization. Cyclic voltammetry revealed that these monomers have excellent polymerization activity, due to their low oxidation potentials (
