Graphical Abstract
Social self-sorting: A binary and a ternary pseudorotaxane, which both contain cucurbituril homologues and share methylviologen as the guest, can self-sort. These two self-sorting pseudorotaxanes were further integrated into one well-defined hetero[3]pseudorotaxane with one symmetrical axle that exclusively selects a pair of different cucurbiturils in a social self-sorting process. Vice versa, a “necklace” of three cucurbit[8]urils is formed, which bind two complementary axles inside their cavities with high fidelity.
