Effective Integrative Supramolecular Polymerization

摘要

Supramolecular self-assembly, which is ubiquitous in biological systems, is a vast source of inspiration for chemists. Supramolecular polymers represent a fascinating class of polymer materials with highly directional and ordered structures. In general, they can be readily prepared from monomelic units by reversible noncovalent interactions, such as hydrogen bonding, metal-ligand coordination, donor-acceptor interaction, host-guest recognition, π-π stacking, and so forth. Because of their intriguing structures and stimuli-responsive properties, the investigation of supramolecular polymers has attracted considerable interest and they have been applied in various fields, such as drug delivery systems, self-healing, and shape-memory materials. Although various strategies have been developed for the assembly of supramolecular polymers, it remains an important challenge to organize structure-controllable and stimuli-responsive supramolecular polymers from discrete and complex components. Inspired by the fact that nature successfully accomplishes intricate functions under extremely complex conditions by using the principles of noncovalent self-assembly together with self-sorting phenomena, chemists have developed some controllable supramolecular polymers by taking advantage of self-sorting.
