摘要 在二价镍配合物催化剂存在下,用3,6-二氯哒嗪与3-庚烷基-2,5-二溴噻吩格氏试剂共聚合成了哒嗪与烷基噻吩共聚物,并利用红外光谱(FT-IR),核磁共振谱(1H-NMR)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、CHC l3等普通溶剂中。共聚物的紫外-可见吸收光谱(UV-v is)中在405 nm处观察到最大吸收峰。用荧光光谱(PL)和热重分析(TGA)对所得聚合物的荧光特性和热稳定性作了初步探讨。 Poly （3-heptylthiophene-alt-pyridazine） was prepared by nickel （Ⅱ） complexes catalyst. Relative copolymer obtained by this method gives isolated yields in 75%. The copolymer was characterized by FT-IR and ^1H-NMR. The results show that the copolymer is in the structure as expected. The obtained copolymer is soluble in DMF, DMSO and CHCl3, etc. The UV-vis spectra of the copolymer show absorption peak at 405 nm in DMSO. Photoluminescence and thermogravimetric behavior of this copolymer are also initially discussed by PL and TGA analysis.
