基于主客体识别作用的光控智能超分子体系的研究进展

Progress in Light-controlled Smart Supramolecular System Based on Host-guest Recognition

利用主客体识别作用赋予材料智能化是目前智能材料研究的一个新方向。通过光可以使客体分子发生可逆的结构改变,如偶氮苯可逆的光致顺反异构,结合环糊精主体分子和客体分子之间可逆形成包结物的能力,可以利用光来设计光控的智能超分子体系。基于上述环糊精和客体分子之间的光控制的主客体识别作用,本文从有机小分子、聚合物和表面三个方面综述了近年来基于主客体识别作用的光控智能超分子体系的研究工作,并对该领域的研究前景进行了展望。

The intellectualization of materials through host-guest recognition becomes a new area in the research of smart materials. Light is used to design light-controlled smart supramolecular system because the properties of guest molecule such as the photoisomerization of azobenzene can be reversibly changed and the inclusion complexes of cyclodextrin and guest molecule can be reversibly formed by light. In this paper, based on the light-controlled host- guest molecular recognition between cyclodextrin and guest molecule, the recent research progress of light-controlled smart supramolecular system based on host-guest recognition is reviewed from three aspects of organic molecule, polymer and surface, and the potential development of the research is prospected.
