摘　　要：采用NaClO氧化联苯二胺成功合成了N,N′-二氯苯醌二亚胺、3,3′-二甲基-N,N′-二氯联苯醌二亚胺和3,3′-二甲氧基-N,N′-二氯联苯醌二亚胺，将其分别与4,6-二氯嘧啶采用金属配合物催化法共聚合，合成了3种新型共聚物：聚（N,N′-二氯联苯醌二亚胺-嘧啶）、聚（N,N′-二氯-3,3′-二甲基联苯醌二亚胺-嘧啶），聚（N,N′-二氯-3,3′-二甲氧基联苯醌二亚胺-嘧啶）。采用傅里叶变换红外光谱、紫外-可见吸收光谱、循环伏安、充放电对共聚物进行结构与性能测试。结果表明：该类共聚物具有一定的电化学活性，每种共聚物均在-0.2~1.0V出现一对氧化还原峰；聚（N,N′-二氯苯醌二亚胺-嘧啶）、聚（N,N′-二氯-3,3′-二甲基联苯醌二亚胺-嘧啶，聚（N,N′-二氯-3,3′-二甲氧基联苯醌二亚胺-嘧啶）的比电容分别为46.2，34.4，23.9F/g。Three new copolymers were synthesized by nickel （Ⅱ） complex catalyzed copolymerization of N,N′-dichlorodiphenoquinone diimine or 3,3′-dimethyl-N,N′- dichlorodiphenoquinone diimine or 3,3′-dimethoxy-N,N′-dichlorodiphenoquinone diimine with 4,6-dichloropyrimidine. The monomers were prepared from corresponding benzidines by sodium hypochlorite oxidation process. The obtained three new copolymers were characterized by Fourier infrared spectroscopy （FTIR）, UV-Vis, cyclic voltammogram and galvanostatic charge-discharge. The results show that the copolymers have certain electrochemical activity and exhibit one redox peaks in the range of -0.2-1.0 V. The specific capacitances of poly（N,N′-p-benzoquinone diimine-co- pyrimidine）, poly（3,3′-dimethyl-N,N′-dichlorodiphenoquinone diimine-co-pyrimidine） and poly（3,3′-dimethoxy-N,N′-dichlorodiphenoquinone diimine-co- pyridine） are 23.9, 34.4, 46.2 F/g respectively.
