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 enantiomeric carbon networks were assembled on the dumbbell joint, and the handedness of the receptors was discriminated, thus leading to the self-sorting of homomeric receptors from a mixture of enantiomeric 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. Leave them to sort themselves out: C120 acts as a dumbbell-shaped joint for the assembly of two tubular receptors (see picture). Enantiomeric receptor carbon networks can be discriminated on the basis of the structures of the contacting edges, thus leading to the self-sorting of homomeric receptors from a mixture of enantiomeric tubes.
