以1,3-二(二苯基膦)丙烷二氯化镍(Ⅱ)作为催化剂,分别合成了2,2′-二噻吩与N,N′-二氯对苯醌二亚胺和2,5-二甲基-N,N′-二氯对苯醌二亚胺的共轭交替共聚物:聚(N,N′-对苯醌二亚胺-2,2′-二噻吩)和聚(2,5-二甲基-N,N′-对苯醌二亚胺-2,2′-二噻吩)。利用红外光谱、紫外可见光谱、循环伏安等测试方法对这2种共聚物进行了表征和性能研究。结果表明:这2种共聚物分别在263、315、410、261、3214、03 nm处出现了紫外吸收峰,对苯二胺上的甲基对共聚物电化学活性具有一定的影响。
Using 1,3-bis (diphenylphosphino) propane nickel (Ⅱ) as catalyst, 2,2’-dithiophene and N, N’-dichloroquinone diimine and 2, Conjugated Alternate Copolymers of 5-Dimethyl-N, N’-Dichlorophenquinone Diimine: Poly (N, N’-p-quinonediimine-2,2’-bithiophene) (2,5-dimethyl-N, N’-p-benzoquinonediimine-2,2’-bithiophene). The two copolymers were characterized and characterized by IR, UV-vis and cyclic voltammetry. The results showed that the two kinds of copolymers showed UV absorption peaks at 263, 315, 410, 261, 3214 and 03 nm, respectively. The methyl groups on the phenylenediamine had some influence on the electrochemical activity of the copolymer.
