Covalent polymers connected by non-covalent interactions constitute a fascinating set of materials known as supramolecular polymer networks (SPNs). A key feature of SPNs is that the underlying covalent polymers endow the resulting self-assembled materials with features, such as structural and mechanical integrity, good processability, recyclability, stimuli-responsiveness, self-healing, and shape memory, that are not recapitulated in the case of classic covalent polymer systems. The unique nature of SPNs derives from the controlled marriage of traditional covalent polymers and macrocycle-based host–guest interactions. As a consequence, supramolecular polymeric networks have played important roles in a number of diverse fields, including polymer science, supramolecular chemistry, materials science, biomedical materials, and information storage technology. In this Review, we summarize advances made in the area of functional SPNs, with a focus on original literature reports appearing in the past five years. The treatment is organized according to the key macrocycle-based host–guest interactions used to produce various SPNs. The role of the underlying polymer backbones is also discussed.

功能性超分子聚合物网络：共价聚合物与基于大环的主体-客体相互作用的结合。

通过非共价相互作用连接的共价聚合物构成了一组引人入胜的材料，称为超分子聚合物网络（SPN）。SPN的一个关键特征是，潜在的共价聚合物赋予所得的自组装材料以结构，机械完整性，良好的可加工性，可回收性，刺激响应性，自我修复性和形状记忆等特性，而这些特性并没有在下文中概述。经典共价聚合物系统的情况。SPN的独特性质源自传统共价聚合物与基于大环的宿主-客体相互作用的控制结合。因此，超分子聚合物网络在许多不同领域发挥了重要作用，包括聚合物科学，超分子化学，材料科学，生物医学材料，和信息存储技术。在这篇评论中，我们总结了功能性SPN领域的进展，重点是过去五年中出现的原始文献报道。根据用于生成各种SPN的关键的基于宏周期的宿主－来宾交互来组织处理。还讨论了基础聚合物主链的作用。
