A fixable supramolecular cyclic polymer based on the cucurbit[8]uril-stabilized π–π interaction

A novel reversible unimolecular cyclization method based on the CB[8]-stabilized interaction in an aqueous environment has been investigated. The dynamic properties of the cyclic PEG chain were monitored by viscometry and DLS. Upon photo-irradiation, the cyclic PEG was covalently fixed and utilized for GPC characterization.
