A viologen-phenylene-imidazole () conjugate, previously shown to be singly complexed by CB[7] and doubly bound by CB[8], is herein shown to form antiparallel triple stacks in water with cucurbit[10]uril (CB[10]), pairwise complexing the guest trimer. The quinary host:guest 2:3 complex showed features assignable to charge-transfer interactions. Under reductive conditions, CB[10] could solubilize a radical, even though CB[10] and reduced are almost insoluble, thereby illustrating a possible new application for CB[10].
一种紫精-亚苯基-咪唑（）共轭物，之前已证明其可被[7]环糊精单络合以及被[8]环糊精双结合，本文展示其在水中与葫芦[10]脲（[10]环糊精）形成反平行三重堆积，成对络合客体三聚体。五元主体：客体2:3络合物显示出可归因于电荷转移相互作用的特征。在还原条件下，[10]环糊精可溶解一种自由基，尽管[10]环糊精和还原态的该自由基几乎不溶，从而说明了[10]环糊精一种可能的新应用。
