摘要：A series of viologen derivatives were synthesised, which can form stable 1:1 inclusion complexes with cucurbit[8]uril (CB[8]) in aqueous solution. The one-electron-reduced viologen radical cations and its dimerisation encapsulated into CB[8] were studied spectroscopically. The monomer-dimer dynamic balance would exist in the molecules containing O-atom, while the molecules without O-atom retain the form of radical monomer in CB[8] cavity. The result demonstrated that the dynamic balance of radical monomer and dimer of these complexes can be modulated by CB[8].
