摘　　要：超分子化学是当前化学领域的研究热点之一。基于环糊精和偶氮化合物的光控超分子可逆体系是近几年在超分子化学基础上发展起来的活跃领域。二者的复合物具有的优秀光学性质使其在光敏型自组装、催化、分子机器设计和智能材料领域受到极大的关注。本文综述了基于环糊精和偶氮化合物的光控超分子可逆体系的研究进展。介绍了该体系的研究背景、优势与原理;根据该体系控制组装体的不同进行了分类总结,包括囊泡、凝胶、轮烷、催化体系、分子触手等;最后结合现阶段的研究情况,对其前景与发展方向进行了展望。Supramolecular chemistry is a hot research topic in current chemistry. The photo-switched supramolecular system based on cyclodextrins and azo compounds is a new area which has been developed in supramolecular chemistry recently. Their complexation with good optical properties attracted great interest in the fields of chemical self-assembly, catalysis, molecular machine design and smart materials. Here, the development of photo-switched supramoleeular system based on cyclodextrins and azo compounds is reviewed. Firstly, the background and principle of the system are introduced. Then, the different aggregates controlled by the supramoleeular system, including vesicles, gels, rotaxanes, catalytic systems and molecule hands, are emphatically described. At last, combined with current development of the system, the prospects are pointed out.
