Synthesis and Properties of Poly(N,N′-p-benzoquinonediimine-co-pyridine)and Poly(2,5-dimethyl-N,N′-p-benzoquinonediimine-co-pyridine) by Metal Complexes Catalyzed

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。

Direct C-N coupling between N,N′-p-benzoquinonediimine 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-dimethylN,N′-p-benzoquinonediimine-co-pyridine） are 126 F/g and 63 F/g respectively.
