Polycyclic fused aromatic pyrrole-based compounds, benzodipyrrole, naphthobipyrrole and their alkylated derivatives, were synthesized and studied electrochemically. Amongst these, naphthobipyrrole having a tetracyclic fused aromatic structure was electrochemically polymerized to give the homopolymer of naphthobipyrrole, poly(naphthobipyrrole), indicating good reactivity of α,α′-pyrrolic positions towards
合成并电化学研究了多环稠合芳族吡咯基化合物苯并二吡咯,萘联吡咯及其烷基化衍生物。其中,具有四环稠合芳族结构的萘联吡咯通过电化学聚合得到萘联吡咯的均聚物,聚萘并吡咯,表明α,α′-吡咯位置对氧化偶合具有良好的反应性。作为合成共聚物的一种战略方法,通过研究β,β′-吡咯位置的反应性,将萘联吡咯与芳基醛共聚,得到聚(芳基亚甲基萘联吡咯)。此外,光学和电化学研究表明该共聚物具有低的光学带隙和升高的HOMO能级。
