Supramolecular polymers based on cyclodextrins

Two types of supramolecular polymers based on cyclodextrins were prepared. One was a host–guest type, and the other was a polyrotaxane type. When a guest part was covalently attached to cyclodextrin, they formed supramolecular dimers, a cyclic daisy chain, supramolecular oligomers, and polymers. t-Boc-cinnamamide-α-cyclodextrin was found to form chiral supramolecular polymers in aqueous solutions. Supramolecular poly[2]rotaxane polymers and supramolecular α,β-cyclodextrin copolymers were obtained. Polyrotaxanes containing β-cyclodextrin or γ-cyclodextrin were prepared. © 2006 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 44: 5113–5119, 2006
