基于冠醚衍生物的超分子聚合物

SUPRAMOLECULAR POLYMERS BASED ON CROWN ETHER DERIVATIVES

自组装现象是生命科学最本质的内容之一,生物体系可以精确地利用非共价键相互作用形成高度有序的功能组装体.受到大自然的启发,近年来利用分子自组装构筑包括超分子聚合物在内的有序聚集体是超分子科学的研究热点.此类组装体不仅在拓扑学上具有重要的意义,而且可以用来制备动态的超分子功能材料.冠醚作为第一代超分子主体化合物,由于其结构简单、易于衍生化,且与多种正离子具有选择性络合作用,越来越广泛地被用作为超分子组装体的构筑单元.本文综述了近年来基于冠醚衍生物超分子聚合物方面的研究.

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.
