Fig. 1. (a) Supramolecular complexation of fullerenes C60 and C70 within the cavity of covalent organic boronate ester cage 1 (molecular structures of inclusion complexes are derived from semiempirical PM6 modeling); (b) schematical representation for the use of C60-cage complexes as shadow masks for a regioselective exohedral C60 functionalization.
