机械互锁分子（MIMs）是一类以轮烷和伪轮烷为主的分子机器，以大环分子为主体，通过主客体络合作用构建分子机器引起了广泛的关注。柱[n]芳烃是一类新型的大环分子，具有刚性柱状结构，具有富电子腔和两个微调边缘。柱[n]芳烃独特的对称刚性结构、易于修饰和优异的主客体络合性能，使其具有形成各种有趣的超分子体系的能力。重要的是，柱[n]芳烃的富π空腔也赋予了它们构建MIMs的能力。本文将全面综述基于[n]芳烃的MIMs的最新进展，重点介绍轮烷和伪轮烷，并重点介绍它们的合成方法。此外，本文还将总结基于[n]芳烃的MIMs的应用，并概述目前基于[n]芳烃的MIMs建设的局限性和前景。
Mechanically inter-locked molecules (MIMs) mainly including rotaxanes and pseudorotaxanes have attracted enormous attention for the fabrication of molecular machines, which can be constructed from macrocyclic molecules as the main building blocks through host–guest complexation. Pillar[n]arenes, as a new class of macrocyclic molecules, have a rigid pillar-like shaped architecture with an electron-rich cavity and two fine-tuneable rims. This unique symmetrical and rigid structure, easy modification and excellent properties in host–guest complexation provides pillar[n]arenes with the ability to form various interesting supramolecular systems. Importantly, the π-rich cavity of pillar[n]arenes also endows them with the ability to construct MIMs. This article will provide a comprehensive review of recent advances in pillar[n]arene-based MIMs, primarily focusing on rotaxanes and pseudorotaxanes, and their synthetic methods will be highlighted. In addition, the applications of pillar[n]arene-based MIMs will be summarized while current limitations and perspectives on the construction of pillar[n]arene-based MIMs will also be outlined.
