摘要: 在二氯-1,3双(二苯基磷)丙烷基镍(Ⅱ)存在下，通过N,N′-二氯苯醌二亚胺和2，5-二甲基N, N′- 二氯苯醌二亚胺与2,5-二溴吡啶的格氏(Grignard) 试剂共聚，得到了两种新型共轭聚合物。采用FT-IR、1HNMR、 UVVis、XRD、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，每种聚合物均在-1.0～2.0 V 出现一对氧化还原峰。聚（N,N′二氯苯醌二亚胺吡啶）和聚（2，5二甲基N, N′二氯苯醌二亚胺吡啶)的比电容分别为126 F/g和63 F/g。

Abstract: Direct C-N coupling between N,N′-pbenzoquinonediimine or 2,5-dimethylN,N′-p-benzoquinonediimine and 2,5-oxazole pyridine Grignard reagent with nickel (II) complex as catalyst was conducted for the preparation of the copolymer. The obtained two new copolymers were characterized by 1HNMR、FT-IR、 UVVis、XRD、cyclic voltammogram and galvanostatic chargedischarge. Results show that the copolymers have certain electrochemical activity and exhibite one redox peaks in the range of -1.0—2.0 V. The specific capacitances of poly(N,N′-p-benzoquinonediiminecopyridine) and poly(2,5-dimethyl-N,N′-p-benzoquinonediimine-co-pyridine) are 126 F/g and 63 F/g respectively.
