Macromolecular Self-Assembly Based on Inclusion Complexation of Cyclodextrins

Recent progresses in molecular self-assembly based on the inclusion complexation between cyclodextrins and various guest macromolecules have been reviewed,which include(1) polyrotaxanes(molecular necklace),polypseudorotaxanes,bis(polypseudorotaxane)s or bis(polyrotaxane)s,molecular tubes or bis(molecular tube)s and supramolecular hydrogels induced by the complexation between cyclodextrins or their dimers and the polymer guests including linear,comb,multi-arms star or hyperbranched ones;(2) linear or hyperbranched supramolecular polymers prepared by the self-assembly of bridged cyclodextrins and their bridged guest molecules;(3) intelligent systems showing stimuli responsive properties including temperature,pH,light or guest molecules;(4) polymeric micelles and hollow spheres made in water by the inclusion between a linear hydrophilic polymer containing cyclodextrin as side groups and a linear hydrophobic polymer with adamantine appendants.In addition,the potential applications of the resultant assemblies are discussed.
