Abstract: We report in this paper the formation of new fullereneterminated selfassembled monolayers(SAMs) from the adsorption of unsymmetrical dialkylmonosulfide compound onto the Au(111) substrate via goldsulfur bonding. The highresolution STM images verified that C60 moieties are located at the outer surface and the XPS results provided clear evidence for S-C cleavage and Au-S bonding during the selfassembling process of this specific C60organosulfide on gold.

Key words: Fullerene, Organosulfide, Gold(111), SAM, STM, XPS
