利用金属催化法分别合成出了2,1,3-苯并硒二唑与N,N′-二氯联苯醌二亚胺、3,3′-二甲基-N,N′-二氯联苯醌二亚胺,3,3′-二甲氧基-N,N′-二氯联苯醌二亚胺的共轭交替共聚物:聚(N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑),聚(3,3′-二甲基-N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑),聚(3,3′-二甲氧基-N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑)。利用凝胶色谱(GPC)、红外光谱、紫外可见光谱以及循环伏安(CV)等对这三种共聚物进行了表征和性能研究。紫外可见光谱分析结果表明,这三种共聚物分别在305nm、421nm,325nm、438nm和330nm、558nm处出现吸收峰,但由于受侧基的影响,聚(3,3′-二甲氧基-N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑)相对于聚(N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑)和聚(3,3′-二甲基-N,N′-联苯醌二亚胺-2,1,3-苯并硒二唑)的共轭程度要高,而且共聚物链上的侧基对其电化学性能也有一定的影响。
2,1,3-benzoselenadiazole and N, N’-dichlorobiphenoquinonediimine, 3,3’-dimethyl-N, N’- Conjugated alternating copolymer of diphenoquinone diimine, 3,3’-dimethoxy-N, N’-dichlorobiphenoquinone diimine: poly (N, N’-diphenoquinonediimine -2,1,3-benzoselenadiazole), poly (3,3’-dimethyl-N, N’-diphenoquinonediimidazole-2,1,3-benzoselenadiazole) Poly (3,3’-dimethoxy-N, N’-diphenoquinonediimine-2,1,3-benzoselenadiazole). The three copolymers were characterized and characterized by gel permeation chromatography (GPC), infrared spectroscopy, UV-vis spectroscopy and cyclic voltammetry (CV). The results of UV-vis spectrum showed that the three copolymers showed absorption peaks at 305nm, 421nm, 325nm, 438nm, 330nm and 558nm respectively. However, due to the influence of pendant groups, the poly (3,3’-dimethoxy- N, N’-diphenoquinonediimine-2,1,3-benzoselenadiazole) to poly (N, N’-diphenoquinodimethane-2,1,3-benzoselenide bis Azole) and poly (3,3’-dimethyl-N, N’-diphenoquinodimelimizin-2,1,3-benzoselenadiazole) have a high degree of conjugation and the degree of conjugation on the copolymer chain The pendant groups also have some influence on their electrochemical properties.
