| Abstract: | Individual C60 molecules adsorbed on a monolayer of 4,4′-dimethyl bianthrone first grown on Cu(111) have been repositioned at room temperature with the tip of a scanning tunneling microscope. The procedure can be applied to C60 without disrupting the 4,4′-dimethyl bianthrone film. Controlled supramolecular repositioning at a molecular interface has allowed us to assemble lateral C60 patterns that define a bimolecular C60-4,4′-dimethyl bianthrone heterojunction on Cu(111). |
