摘要
以盐酸联苯胺为原料,经过重氮偶联、烷基化合成了预聚物,再与联苯胺反应生成主链同时含有偶氮和席夫碱结构的新型线性共轭聚合物,利用1H NMR,FT-IR和HR-MS(ESI)对中间体及聚合物结构进行表征,通过紫外可见吸收光谱及荧光发射光谱对其光学性能进行了研究。
Using benzidine hydrochloride as raw material.The prepolymer was synthesized by diazo-coupling and alkylation.A novel linear conjugated polymer whose main chain contains azo and schiff base units was synthesized by prepolymer reacted with benzidine.The structures of intermediate and polymer were characterized by 1H NMR,FT-IR and HR-MS(ESI).The optical properties were investigated thoroughly by UV-Vis absorption spectroscopy and fluorescence emission spectroscopy.
