Abstract

A carbonaceous dumbbell was able to spontaneously glue two tubular receptors to form a unique two-wheeled composite through van der Waals interactions, thus forcing the wheel components into contact with each other at the edges. In the present study, two tubular receptors with enantiomericcarbon networks were assembled on the dumbbell joint, and the handedness of the receptors was discriminated, thus leadingto the self-sorting of homomeric receptors from a mixture ofenantiomeric tubes. The crystal structures of the composites revealed the structural origins of the molecular recognition driven by van der Waals forces as well as the presence of a columnar array of C120 molecules in a 1:1 composite.
