The nature of mechanically interlocked molecules (MIMs) has continued to encourage researchers to design and construct a variety of high-performance materials. Introducing mechanically interlocked structures into polymers has led to novel polymeric materials, called mechanically interlocked polymers (MIPs). Rotaxane-based MIPs are an important class, where the mechanically interlocked characteristic retains a high degree of structural freedom and mobility of their components, such as the rotation and sliding motions of rotaxane units. Therefore, these MIP materials are known to possess a unique set of properties, including mechanical robustness, adaptability and responsiveness, which endow them with potential applications in many emerging fields, such as protective materials, intelligent actuators, and mechanisorption. In this review, we outline the synthetic strategies, structure-property relationships, and application explorations of various polyrotaxanes, including linear polyrotaxanes, polyrotaxane networks, and rotaxane dendrimers.
机械互锁分子（MIMs）的性质不断鼓励研究人员设计和构建各种高性能材料。将机械互锁结构引入聚合物中，导致了新型聚合物材料，称为机械互锁聚合物（MIPs）。基于轮烷的 MIP 是一个重要的类别，其中机械互锁特性保持其组件高度的结构自由度和迁移性，例如轮烷单元的旋转和滑动运动。因此，这些 MIP 材料被认为具有独特的一组特性，包括机械坚固性、适应性和响应性，这使它们在许多新兴领域具有潜在的应用，如防护材料、智能致动器和机械吸附。在这篇综述中，我们概述了各种聚轮烷的合成策略、结构-性能关系和应用探索，包括线性聚轮烷、聚轮烷网络和轮烷树状大分子。
