Sequence-specific self-sorting of the binding sites of a ditopic guest by cucurbituril homologues and subsequent formation of a hetero[4]pseudorotaxane

CB6, CB7, and CB8 recognize and self-sort the binding sites according to their size, shape, and chemical nature. In the presence of both CB6 and CB8 a hetero[4]pseudorotaxane is formed. © 2009 Wiley-VCH Verlag GmbH & Co.
