Supramolecular polymers have attracted plenty of interest in the scientific community; however, developing controllable methods of supramolecular polymerization remains a serious challenge. This article reviews some recent developments of methods for supramolecular polymerization from controllable fabrication to living polymerization. Three facile methods with general applicability for controllable fabrication of supramolecular polymers have been established recently: the first method is a self-sorting approach by manipulating ring-chain equilibrium based on noncovalent control over rigidity of monomers; the second is covalent polymerization from supramonomers formed by noncovalent interactions; and the third is supramolecular interfacial polymerization. More excitingly, living supramolecular polymerization has been achieved by two elegant strategies, including seeded supramolecular polymerization under pathway complexity control and chain-growth supramolecular polymerization by metastable monomers. It is anticipated that this review may provide some guidance for precise fabrication of supramolecular polymers, leading to the construction of supramolecular polymeric materials with controllable architectures and functions.
超分子聚合物已在科学界引起了广泛关注；然而，开发可控的超分子聚合方法仍然是一项严峻的挑战。本文综述了超分子聚合方法从可控制备到活性聚合的一些最新进展。最近已经建立了三种具有普遍适用性的超分子聚合物可控制备的简便方法：第一种方法是通过基于对单体刚性的非共价控制来操纵环链平衡的自分类方法；第二种是由非共价相互作用形成的超单体进行的共价聚合；第三种是超分子界面聚合。更令人兴奋的是，通过两种巧妙的策略实现了活性超分子聚合，包括在途径复杂性控制下的种子超分子聚合和由亚稳单体进行的链增长超分子聚合。预计这篇综述可能为超分子聚合物的精确制备提供一些指导，从而实现具有可控结构和功能的超分子聚合物材料的构建。
