摘要:

Monolayer coverages of C60on a gold substrate have been studied using scanning tunneling microscopy. The images reveal various packing arrangements and reproducible intramolecular contrasts of the C60molecules. We find thatapproximatelyeveryothercarbonatomis highlighted on the π‐electron surface of the molecule as a result of a preferential electron transfer from the gold substrate, in agreement with a theoretical analysis of the high‐lying π‐electron density of a C60molecule adsorbed on metallic surfaces.
