偶氮嵌段共聚物合成、自组装与光响应性

Synthesis,self-assembly and photoresponsive properties of azobenzene-containing block copolymers

含偶氮苯基团的嵌段共聚物兼具偶氮聚合物和嵌段共聚物的特点,可自组装形成具有特殊光响应性能的各种纳米/亚微米结构,在光信息存储、传感器、药物输送、光控智能材料等领域有重要的应用前景。本文对本课题组近年来在含强推拉电子型偶氮生色团的嵌段共聚物合成、自组装与光响应性方面的研究工作进行简要综述。

Azobenzene-containing block copolymers can self-assemble into a variety of supramolecular structures with unique photoresponsive properties,which can be potentially used in many fields such as information storage,sensors,drug delivery,and smart nano/micro-materials.This paper reviews the study of the synthesis,self-assembly and photoresponsive properties of block copolymers bearing strong push-pull azo chromophores,which has recently been carried out in authors＇ laboratory.
