以2,5-二甲基对苯二胺和对苯二胺为原料,在次氯酸钠溶液中氧化合成了2,5-二甲基-N,N′-二氯对苯醌二亚胺和N,N′-二氯对苯醌二亚胺后,采用金属催化法合成了前述单体与2,1,3-苯并硒二唑的交替共聚物,其产率分别为45.0%,49.4%。利用红外光谱、紫外-可见吸收光谱和循环伏安等对共聚物进行了表征及电化学测试。结果表明,两种共聚物都分别在338,462nm和338,392nm处出现了吸收峰,都具有一定的电化学活性;对这两种聚合物进行了碘掺杂,并对其掺杂后的电化学活性进行了初步探讨。
Using 2,5-dimethyl-p-phenylenediamine and p-phenylenediamine as raw materials, 2,5-dimethyl-N, N’-dichloroquinone diimine and N , N’-dichloro p-benzoquinone diimine, an alternating copolymer of the above monomers and 2,1,3-benzoselenadiazole was synthesized by metal catalysis with the yields of 45.0%, 49.4% . The copolymers were characterized and electrochemically tested by FTIR, UV-Vis absorption and cyclic voltammetry. The results show that the two copolymers have absorption peaks at 338,462 nm and 338,392 nm, respectively, and both have certain electrochemical activity. The two polymers were doped with iodine, and their doped electrochemical Activity was initially discussed.
