摘　　要：机械互锁结构是一类具有独特性质的超分子实体,不但在拓扑学上具有重要的意义,而且是制备分子机器的结构基础,它们在纳米技术、生物、材料等领域有着巨大的应用前景。本文概述了通过配位作用组装制备轮烷、索烃及其他机械互锁结构研究的新进展,着重关注以金属配位作用作为一种构建方式与主客体识别协同组装制备机械互锁结构。由于金属配位键具有易成键、动态可逆、可调控等优点,采用金属配位作用构建机械互锁结构不仅可以大大地提高制备效率,而且有利于实现对机械互锁分子的可逆调控。Mechanically interlocked structures are a kind of supramolecular entities with unique properties. They have attracted much attention not only because of their fascinating aspect of topologies, but also due to their great potential applications in nanotechnology, biology, and material science, as well as important bases for the preparation of molecular machines. This article summarizes new progress in the preparation of rotaxanes, catenanes, and other mechanically interlocked structures assembled via coordination interactions, especially focuses on the examples using metal-mediated coordination interactions as building ways cooperating with hostguest chemistry. Because coordination bonds are easy bonding, dynamically reversible, and easily controllable, the usage of metal-mediated coordination for constructing mechanically interlocked structures can greatly improve the preparation efficiency, and benefit to realizing the reversible regulation of mechanically interlocked structures.
