摘要
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.
In this paper poly （thiophene-alt-pyridazine） was prepared by nickel（Ⅱ） complexes catalysed. Relative copolymers obtained by this method give isolated yields in 75%. The copolymers were characterized by FT-IR and ^1H-NMR. The results from FT-IR and 2H-NMR showed that the copolymers were in the structure as expected. The obtained copolymers were soluble in DMF, DMSO and CF3COOH, etc. The UV-vis spectra of the copolymers showed absorption peaks at 410 nm in DMSO. Crystallinity and thermogravimetric behavior of this copolymer were also initially discussed by using XRD and TGA analyses.
