Abstract:Supramolecular chemistry is a kind of non-covalent bonding, which mainly represents hydrogen bonding, metal-ligand, guest-host interaction, etc. Although these interactions are relatively weak compared with covalent bonding, a large number of supramolecular interactions can form a dynamic system with high mechanical strength. Many biological assemblies are connected by non-covalent bonding, which have attracted the research interest of many scholars. In this review, the concept and history of supramolecular dynamic chemistry were summarized, and on this basis, the different supramolecular interactions of materials were expounded thoroughly, that is, based on hydrogen bond, metal ligand, ion, host-guest and π-π interaction. The construction of self-healing materials based on dynamic supramolecular chemistry provides a theoretical basis and scientific value for the design and preparation of intelligent materials.
