以二氯-1,3-双(二苯基磷)丙烷基镍(Ⅱ)为催化剂,通过3,6-二氯哒嗪格氏试剂与3,6-二溴-N-戊烷基咔唑共聚得到了一种新型共轭聚合物,并使用IR和1H-NMR等测试手段对单体和聚合物的结构进行了表征。该合成方法所得的共聚物收率为75%,共聚物在N,N-二甲基酰胺(DMF)、二甲基亚砜(DMSO)等极性溶剂和CF3COOH、CH3SO3H、HCOOH等常用有机酸中具有较好的溶解性。用红外(FT-IR)、紫外-可见吸收光谱(UV-vis)、荧光光谱(PL)、X射线衍射、循环伏安(CV)等对聚合物的吸收光谱特性、结晶性和电化学活性进行了探讨。结果表明:聚合物具有较高的发光强度,是一种还原型聚合物,结晶性比较差。
Using dichloro-1,3-bis (diphenylphosphino) propane nickel (Ⅱ) as catalyst and 3,6-dichloropyridazine Grignard reagent and 3,6-dibromo-N- A novel conjugated polymer was obtained by the copolymerization of azole and the structure of the monomer and polymer was characterized by means of IR and 1H-NMR. The yield of the copolymer obtained in the synthesis method is 75%. The copolymer is prepared in a polar solvent such as N, N-dimethylformamide (DMF) and dimethylsulfoxide (DMSO) and a common organic acid such as CF3COOH, CH3SO3H and HCOOH. In the better solubility. The absorption spectra, crystallinity and electrochemical activity of the polymers were characterized by FT-IR, UV-vis, PL, X-ray diffraction and cyclic voltammetry (CV) Discussed. The results show that the polymer has high luminescence intensity and is a kind of reduced polymer with poor crystallinity.
