1,3-双(二苯基瞵)丙烷基二氯化镍存在下,3,6二氯哒嗪与1,4二溴苯格氏试剂共聚,庚氧基取代苯与3,6二氯哒嗪格氏试剂共聚得到了哒嗪类新型共轭共聚物。并用FTIR、NMR对中间体和聚合物的结构进行了表征。采用XRD测试对共聚物结晶性进行了讨论。该合成方法所得的共聚物收率分别为75%和67%。其中含有烷氧基苯单元的共聚物在DMF、DMSO等极性溶剂和有机酸中具有良好的溶解性。共聚物的紫外可见光谱中,分别在310nm、345nm等处出现最大吸收峰。XRD结果表示共聚物具有一定的结晶性。
In the presence of 1,3-bis (diphenylphosphino) propane nickel dichloride, 3,6-dichloropyridazine was copolymerized with 1,4-dibromobenzene Grignard reagent, and heptyloxy-substituted benzene was reacted with 3,6-dichloro- Pyridazine Grignard reagent copolymerization of pyridazine new conjugated copolymer. The structures of intermediates and polymers were characterized by FTIR and NMR. The crystallinity of copolymer was discussed by XRD test. The yield of the copolymer obtained by this synthesis method was 75% and 67%, respectively. Among them, the copolymer containing alkoxyphenyl units has good solubility in polar solvents such as DMF and DMSO and organic acids. In the UV-Vis spectrum of the copolymer, the maximum absorption peak appears at 310nm, 345nm and so on. XRD results show that the copolymer has certain crystallinity.
