Abstract
Cyclodextrins (CDs) have been found to form inclusion complexes with various polymers with high selectivities to give stoichiometric compounds in crystalline states. α-CD formed complexes with poly(ethylene glycol)(PEG) of molecular weight higher than 300, although β-CD did not form complexes with PEG of any molecular weight. However, β-CD formed complexes with poly(propylene glycol)(PPG), although α-CD did not form complexes with PPG of any molecular weight. γ-CD formed complexes with poly(methyl vinyl ether)(PMVE), though α- and β-CD did not form complexes with PMVE. Polyrotaxanes in which many CDs are threaded on a single PEG chain were prepared by capping the chain ends of the complex with bulky groups. The neighboring CDs in a polyrotaxane are crosslinked by epichlorohydrin and then stoppers at the both ends and the polymer chain of the crosslinked polyrotaxane were removed by strong base to give a tubular polymer, a molecular tube.
