A heterowheel [3]pseudorotaxane was prepared by integrating two binary inclusion complexes of β-cyclodextrin-hydroxynaphthalene (β-CD·3) with a cucurbit[8]uril-viologen derivative (CB[8]·2), in which simultaneous molecular recognition of the adamantine moiety in 2 by β-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.
通过整合 β-环糊精-羟基萘（β-CD·3）与葫芦[8]脲-二茂铁衍生物（CB[8]·2）的两个二元包合络合物，制备了一个杂轮[3]伪轮烷，其中 2 中的金刚烷部分与 β-CD 的分子识别以及 3 与 CB[8]腔中 2 的二茂铁核的电荷转移相互作用是形成季铵配合物的两个关键因素。
