The azomethine with a donor-acceptor-acceptor-acceptor-donor structure has been synthesized and characterized. Azomethine exhibited luminescence properties and a positive solvatochromic effect. Electropolymerization on terminated triphenylamine groups was used to obtain a thin layer of the polyazomethine . Further investigation of oxidation/reduction properties of via cyclic voltammetry showed that the polymer undergoes two reversible oxidation/reduction processes due to the presence of tetraphenylbenzidine moieties. Electrochromic properties of the polyazomethine were investigated via spectroelectrochemistry. It was observed that the polymer in its neutral state is orange, and the color changes to green upon electro-oxidation. The stability of the polymer during multiple oxidation/reduction cycles, response times, and coloration efficiency were also investigated.
具有供体-受体-受体-受体-供体结构的偶氮甲碱已被合成并表征。偶氮甲碱表现出发光特性和正溶剂化显色效应。利用在端基三苯胺基团上进行电聚合来获得聚偶氮甲碱的薄层。通过循环伏安法对其氧化/还原性质进行的进一步研究表明，由于四苯基联苯胺部分的存在，该聚合物经历两个可逆的氧化/还原过程。通过光谱电化学研究了聚偶氮甲碱的电致变色性质。观察到该聚合物在中性状态下为橙色，电氧化后颜色变为绿色。还研究了该聚合物在多次氧化/还原循环过程中的稳定性、响应时间和显色效率。
