摘　　要：分子梭作为分子机器的一种主要类型,大多是建立在主客体识别的基础上的,其在分子开关、分子逻辑门、信息存储等领域有着重要的潜在应用价值,是超分子化学领域的研究热点之一。本文介绍了分子梭的概念、原理,详细归纳了具有刺激响应型的分子梭。并且,按照外界刺激源的不同,将刺激响应型分子梭分为光驱动、p H驱动、氧化还原驱动以及多重驱动的分子梭。阐述了不同驱动方式的分子梭的结构特点、运动规律、研究进展及潜在应用,分析了刺激响应型分子梭目前面临的问题,并对其今后的发展趋势做了展望。Molecular shuttle,as a kind of molecular machines,is one of the research intriguing interest in supramolecular chemistry. Molecular shuttles are mostly based on the host-guest recognition. They have potential applications in many areas such as nano-structured functional materials,molecular switches,molecular logic gates,memory devices and so on. In this paper,the progress in molecular shuttles is systematically reviewed,including the conception,mechanisms and potential applications,focusing on the molecular shuttles driven by external-stimuli. According to the difference of external-stimuli,molecular shuttles can be classified into light driven,pH-driven,redox-driven and multimode-driven molecular shuttles. The structure characteristics,motion law and progress of molecular shuttles driven by different external-stimuli,are elaborated. The problem of responsive molecular shuttles researches is analyzed,and the future development of responsive molecular shuttles is prospected.
