Monofunctionalised cucurbit[6]uril synthesis using imidazolium host-guest complexation

Abstract

Monohydroxylated cucurbit[6]uril was prepared for the first time through the controlled oxidation of CB[6] in the presence of a tailor-made bisimidazolium guest, as verified by H-1 NMR, ESI-MS and X-ray crystallography. Further chemical modification of monohydroxylated CB[6] was also readily achieved.</p
