SUPRAMOLECULAR POLYMERS BASED ON CROWN ETHER DERIVATIVES

Self-assembly is ubiquitous in nature.Biological systems utilize nonocovalent forces to control the self-assembly process precisely,resulting in the formation of complicated structures with multiple functions.Inspired by the structure of biological macromolecules,chemists are engaged in developing highly-ordered artificial supramolecular assemblies such as supramolecular polymers,which exhibit great significance in the formation of various supramolecular architectures,and more importantly,the potential applications of dynamic supramolecular materials.In recent years more and more attentions have been paid to crown ethers,one of the most commonly used hosts in supramolecular chemistry,which serve as the building blocks to construct functional supramolecular assemblies due to their facilitated syntheses,convenient structure modification and unique complexation properties with a variety of guest molecules.This review focuses on supramolecular polymers based on crown ether derivatives.
