A heterowheel [3]pseudorotaxane was prepared by integrating two binary inclusion complexes of beta-cyclodextrin-hydroxynaphthalene (beta-CD .3) with a cucurbit[8]uril-viologen derivative (CB[8] .2), in which simultaneous molecular recognition of the adamantine moiety in 2 by beta-CD and the charge-transfer interaction of 3 with the viologen nucleus of 2 in the cavity of CB[8] are two crucial factors for the formation of the quaternary complex.
