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。
Pyridazine and alkylthiophene copolymers were copolymerized with 3,6-dichloropyridazine and 3-heptyl-2,5-dibromothiophene Grignard reagent in the presence of a divalent nickel complex catalyst. Its structure and properties were characterized by Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (1H-NMR). The yield of the copolymer obtained in the synthesis method was 75%, and was dissolved in a common solvent such as DM F, DM SO, CHCl 3 and the like. The maximum absorption peak at 405 nm was observed in the UV-Vis absorption spectrum of the copolymer. Fluorescence spectra (PL) and thermogravimetric analysis (TGA) were used to investigate the fluorescence and thermal stability of the obtained polymers.
