Supramolecular Assembly of Individual C(60) on a Monolayer of 4,4'-Dimethylbianthrone Molecules

We use a scanning tunneling microscope (STM) to reposition individual C(60) molecules adsorbed on a well-ordered monolayer of 4,4'-dimethylbianthrone (DMB), first grown on Cu(111). The surface binding energies and diffusion barriers of C(60) molecules are substantially modified when the molecules bond to DMB instead of to Cu. The tip of the STM can be used to reposition single, isolated C(60) molecules across the surface without disrupting the DMB film underneath.
