摘　　要：以4,7-二溴-2-十二烷基-1,2,3-苯并三氮唑和带不同碳数烷基的3-烷基噻吩格式试剂为单体,通过Ni(Ⅱ)配合物催化法分别合成了带有丁基、辛基和十二烷基侧链的共聚物,并采用FT-IR、1H-NMR对其化学结构进行了表征。所得共聚物的M n分别为0.57×104,0.59×104和0.49×104g/mol,其M w(g/mol)分别为1.25×104,1.24×104和0.96×104g/mol。所得共聚物在CHCl3、THF等溶剂中具有较好的溶解和成膜性。聚合物在CHCl3溶液中的紫外-可见最大吸收波长分别为433,432和415 nm,共聚物在固态薄膜状态下的紫外-可见最大吸收波长与溶液比较约红移8nm。3种共聚物表现出较好的荧光性能。Alternating copolymers of benzotriazole and thiophene containing different alkyl rode chain were pre- pared by metal complex catalyses method. The chemical structure and basic properties of obtained copolymers were characterized by 1H-NMR, FT-IR, UV-Vis, Fluorescence spectroscopy and gel permeation chromatogra- phy. The obtained polymers can be solved easily in common organic solvents such as CHC13and THF. UV-Vis maximum absorbance in CHC13 of these copolymers appeared about 433,432 and 415 nm respectively. Number average molecular weights （Mn） of the polymers was about 0.57 X 10^4-0.49 X 10^4. The polymers showed better fluorescence characteristics and electrochemical activity.
