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-IR1、H-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。
N, N’-dichlorobenzoquinonediimine and 2,5-dimethyl-N, N ’-dihydroquinone diimine in the presence of dichloro-1,3-bis (diphenylphosphino) -dichlorobenzoquinone diimine with 2,5-dibromopyridine Grignard reagent, two novel conjugated polymers were obtained. The structure and properties of the copolymer were tested by FT-IR1, H-NMR, UV-Vis, XRD, cyclic voltammetry and charge-discharge. The results show that these copolymers have a certain electrochemical activity. Each polymer exhibits a pair of oxidation-reduction peaks at -1.0 ~ 2.0 V. The specific capacitances of poly (N, N’-dichlorobenzoquinone diimine-pyridine) and poly (2,5-dimethyl-N, N’-dichloroquinone diimine-pyridine) were 126 F / g and 63 F / g.
