Abstract
The photodimerization of water-insoluble 2-naphthalene-labeled poly(ethyl glycol) (N-Pn-N) in cucurbit[8]uril (CB[8]) aqueous solution was investigated. UV-vis, fluorescence, and 1H NMR analysis reveal that CB[8] can encapsulate N-Pn-N to make a stable 1:1 inclusion complex N-Pn-N@CB[8] in aqueous solution. Irradiation of N-Pn-N in the CB[8] aqueous solution results in intramolecular photocycloaddition with remarkable selectivity and efficiency, whereas no photodimer could be detected in host-free solution.Entities:
