Supramolecular Isomerism in Caviplexes.
Stereoisomeric complexes of an open-ended cavitand and its guest molecules (shown schematically) were detected, and complexes within caviplexes were introduced. Some control can be exerted on the stereoisomerism through methylation of the guest. The symbols "0" and "1" represent different ends of the guest molecule.
