Abstract

We find that C₅₉N exists as a monomer on Si(111) and Si(100) surfaces, in contrast to the dimerized state ((C₅₉N)₂) it adopts in the bulk azafullerene solid. A combination of scanning tunnelling microscopy, photoelectron spectroscopy and X-ray absorption measurements indicates that, as for C₆₀, the chemical bond between C₅₉N and the Si(111)-(7×7) surface involves the formation of covalent Si-C bonds. We argue that the strong C₅₉N-surface interaction on both Si(111) and Si(100) precludes molecular diffusion and thus prohibits the formation of dimers. The dominant role of molecule-surface, as opposed to intermolecular interactions is confirmed by scanning tunnelling microscope-based molecular manipulation experiments.
