在二价镍配合物催化剂存在下,用3,6-二氯哒嗪与2,5-二溴噻吩格氏(G rignard)试剂共聚合成了哒嗪与噻吩共聚物,并利用红外光谱(FT-IR),核磁共振谱(1H-NM R)等对其结构和性能进行了表征.该合成方法所得共聚物的收率为75%,而且溶解于DM F、DM SO等普通溶剂.共聚物的紫外-可见吸收光谱(UV-v is)中在410nm处观察到最大吸收峰.用粉末X-射线衍射(XRD),热重分析(TGA)对所得聚合物的结晶性和热稳定性也作了初步探讨.
Pyridazine and thiophene copolymers were copolymerized with 3,6-dichloropyridazine and 2,5-dibromothiophene Grignard reagent in the presence of a divalent nickel complex catalyst and characterized by FT-IR (FT -IR) and nuclear magnetic resonance (1H-NMR) were used to characterize the structure and properties of the copolymer.The yield of the copolymer obtained was 75%, and it was dissolved in common solvents such as DM F and DM SO. The maximum absorption peak was observed at 410 nm in the UV-Vis absorption spectrum The crystallinity and thermal stability of the resulting polymer were also evaluated by powder X-ray diffraction (XRD), thermogravimetric analysis (TGA) Made a preliminary discussion.
