Abstract
The binding stoichiometry of a host–guest complex can be effectively controlled by the redox chemistry of the guest∶ a 1∶1 inclusion complex of methylviologen dication (MV2+) in cucurbit[8]uril (CB[8]) converts completely and reversibly to a 2∶1 inclusion complex of cation radical (MV+˙) in CB[8] upon the reduction of the guest.Keywords
