Construction of supramolecular structures from cyclodextrins, polymers

摘要: Abstract Cyclodextrins (CDs) have been found to form inclusion complexes with various polymers high specificity give stoichiometric compounds in crystalline states. In these complexes, polymer chains were threaded into cyclodextrins and recognized by the host. For example, α-cyclodextrin (α-CD) formed poly(ethylene glycol) (PEG) of molecular weight higher than 200, although β-CD did not PEG any weight. However, poly(propylene (PPG) weights which α-CD complexes. γ-CD poly(methyl vinyl ether) (PMVE), though α-, PMVE. oligoethylene, but only polyisobutylene over 500. The structures properties studied spectroscopic methods. Polyrotaxanes many CDs are on a single chain prepared capping ends bulky groups.
