3-次甲基（4-丁氧基苯胺）噻吩与吡啶、3-丁基噻吩共聚物的金属配合物催化法合成及性能

摘要

A new Schiff-base monomer,2,5-dibromo-3-methyne（4-butoxylaniline）thiophene,was synthesized by Schiff-base reaction,and two new copolymers,poly[3-methyne（4-butoxylaniline）thiophene-co-3-butylthiophene]（copolymerⅠ） and poly[3-methyne（4-butoxylaniline）thiophene-co-pyridine]（copolymerⅡ）,were prepared by using nickel（Ⅱ） complex as catalyzer.The chemical structures of polymers were verified by 1H-NMR and FT-IR.Electrical and optical properties were characterized by UV-Vis,PL and cyclic voltammogram.Results show that solutions of copolymerⅠand copolymerⅡemit yellow-green light in chloroform,with maximum PL emission at 540 nm and 516 nm,respectively.Moreover,the copolymers have certain electrochemical activity.%通过Schiff-base法合成了侧链含席夫碱的新型噻吩单体2,5-二溴-3-次甲基（4-丁氧基苯胺）噻吩,用Ni（Ⅱ）催化剂[二氯-1,3-双（二苯基磷）丙烷基镍（Ⅱ）]合成了新型共轭共聚物聚[3-次甲基（4-丁氧基苯胺）噻吩-共-3-丁基噻吩]（共聚物Ⅰ）和聚[3-次甲基（4-丁氧基苯胺）噻吩-共-吡啶]（共聚物Ⅱ）。采用FT-IR、1H-NMR对2种共聚物的化学结构进行了表征,利用UV-Vis、PL、循环伏安等测试方法对其进行光、电性能测试。结果表明：共聚物在氯仿溶液中发黄绿光,共聚物Ⅰ和共聚物Ⅱ的最大发射峰分别位于540 nm和516 nm,该类共聚物均具有一定的电化学活性。
