Buckyball bearings: C60 complexes with zinc octaethylporphyrin (ZnOEP) were deposited in the hexagonal pores of the highly stable honeycomb network generated by thermal dehydrogenation of 4,9-diaminoperylene-quinone-3,10-diimine on a Cu(111) surface (see picture). The piece-by-piece assembly of the weakly aggregated ZnOEP–C60 complex, which may be viewed as a “supramolecular bearing”, was achieved with the aid of an STM tip.
