Photoresponsive supramolecular switches refer to these host‐guest systems that can be reversibly shifted between different states by light stimuli. Such photoswitchable systems feature the presence of non‐covalent bonding interactions with light‐responsive moieties (e. g., azobenzene and stilbene, spiropyran and diarylethene, coumarin and anthracene), and have been applied in a variety of fields, such as drug delivery, tissue engineering and smart materials with the advantage of being able to operate cleanly and remotely in a spatiotemporally‐controlled fashion. Alternating UV/visible light irradiation can reversibly regulate the binding affinity or assembly/disassembly of the systems. This minireview summarizes recent progress (2016 and after) on the development of photoswitchable host‐guest systems, including the structural designs of these molecular switches and their applications in solution and solid states. Better knowledge of them is essential for the understanding of host‐guest phenomena, molecular machines, and also for the preparation of novel applied materials in the future.

光响应超分子开关的最新进展

光响应性超分子开关是指这些主客体系统，可以通过光刺激在不同状态之间可逆地移动。此类光开关系统具有与光响应部分（例如，偶氮苯和lb，螺并吡喃和二芳基乙烯，香豆素和蒽）存在非共价键相互作用的特性，并已应用于多种领域，例如药物递送，组织工程和智能材料，其优势在于能够以时空受控的方式进行清洁和远程操作。交替的紫外线/可见光照射可以可逆地调节系统的结合亲和力或组装/拆卸。本小结概述了光开关主机系统的最新进展（2016年及以后），包括这些分子开关的结构设计及其在溶液和固态中的应用。更好地了解它们对于理解客体现象，分子机器以及将来制备新型应用材料至关重要。
