Two new kinds of dithienylpyrroles bearing anthraquinone units have been prepared by the Knorr–Paal condensation between 1,4-di(thiophen-2-yl)butane-1,4-dione and 1-/2-amino-anthraquinone. The corresponding polymer films were successfully synthesized via electropolymerization. The electrochemical, electro-optical properties and electrochromic behavior of the two polymer films were further investigated
通过1,4-二(噻吩-2-基)丁烷-1,4-二酮和1- / 2-氨基-蒽醌之间的克诺尔-帕尔缩合反应,制备了两种带有蒽醌单元的二噻吩基吡咯。通过电聚合成功地合成了相应的聚合物膜。通过热重分析,循环伏安法和紫外可见吸收光谱进一步研究了两种聚合物薄膜的电化学,电光性质和电致变色行为。结果表明,两种聚合物薄膜在接近300°C的温度下均具有热稳定性。两种电活性聚合物膜都呈现出稳定且定义明确的可逆氧化还原过程,以及从黄色(处于还原态)到灰色(呈中性态)然后到蓝色(处于氧化态)的多色电致变色。
