摘　　要：偶氮液晶嵌段共聚物是指分子中带有偶氮苯基团的液晶嵌段共聚物.偶氮液晶嵌段共聚物兼具偶氮聚合物的光响应性和液晶嵌段共聚物自组装形成多尺度有序结构的特性,是一类有重要应用前景的新材料.本文简要综述了近10年来偶氮液晶嵌段共聚物的研究进展,以几种典型的偶氮液晶嵌段共聚物为例,介绍嵌段共聚物在本体以及溶液状态下自组装,自组装形貌的光致变化,以及偶氮液晶嵌段共聚物在光全息存储领域等的研究进展.Azobenzene-containing liquid crystalline block copolymers represent a special category of block copolymers and functional materials.The combination of photoresponsive properties of azo polymers and hierarchical supramolecular structures of liquid crystalline block copolymers leads to their unique characteristics and functions.Research in this field has generated a number of new block copolymers and recorded some newly discovered properties of the copolymers.In this review,a few examples were chosen to discuss the recent developments in this area with emphasis on the photoinduced morphological changes and holographic properties of this type of polymers and materials.
