The growing synergy between supramolecular chemistry and polymer synthesis is driven by the realization that the dynamic nature of non-covalent interactions may bring new properties and material performance to the field of polymer science. This is manifested in the area of block copolymer self-assembly where supramolecular systems have displayed remarkable morphologies and properties not attained in classic covalent systems. This review article examines the broad strategy of combining phase separation of block copolymers with the dynamic properties of supramolecular interactions.
