Polyrotaxanes in which many cyclodextrins are entrapped along a polymer chain have been prepared. Molecular tubes have been prepared by binding neighboring cyclodextrins with short biding reagents and then removing a polymer chain by cleaving stopper groups of the polyrotaxane. Artificial polymerases with a molecular clamp were designed and prepared. Cyclodextrins were found to initiate ring opening polymerization of some lactones with high selectivity. Monomers were found to be inserted between cyclodextrins and the growing chain. Cyclodextrins dimers were found to be much better catalysts for the ring opening polymerization. One of the cyclodextrins plays an important role as a molecular clamp as shown in DNA polymerases in nature.
