Supramolecular Polymer Chemistry:Past,Present,and Future

The interplay between polymer science and supramolecular chemistry leads to the formation of various supramolecular polymeric systems,with their functions determined by the range of supramolecular structures formed by self-assembly(Fig.1).In general,there are two main approaches to fabricate supramolecular polymeric systems.In approach A,covalently linked polymers are used as building blocks to self-assemble into supramolecular polymeric systems on the basis of noncovalent interactions.In approach B,bi-functional monomers are designed and synthesized on the basis of covalent bonds,
