AbstractThe adsorption of four fullerene derivatives, including Re(C(60)Me(5))(CO)(3), Ru(C(60)Ph(5))Cp, C(60)(C(6)H(4)C(6)H(4)-COOH)(5)Me, and C(60)(C(6)H(4)-CC-SiMe(2)C(12)H(25))(5)Me, on a Au(111) surface has been investigated by scanning tunneling microscopy (STM) and cyclic voltammetry. High-resolution STM images reveal that Re(C(60)Me(5))(CO)(3) forms a well-ordered (2 root 3 x 2 root 3)R30 degrees structure. Different from C(60) on Au(111), the so-called "in-phase" structure is not found with the attachment of methyl and Re(CO)(3) groups. With the increase of substituent size, disordered adlayers have been observed for Ru(C(60)Ph(5))Cp and C(60)(C(6)H(4)C(6)H(4)-COOH)(5)Me. However, the individual molecules could be distinguished in STM images, suggesting that the two molecules interact strongly with the Au(111) surface. When the substituent size is further increased, a multilayered structure is formed for C(60)(C(6)H(4)-CC-SiMe(2)C(12)H(25))(5)Me. This is because of molecular aggregation in the bulk solution, which occurs at very low concentration. These results indicate that the structures of fullerene derivatives play an essential role in adlayer formation through adjusting molecule-substrate and molecule-molecule interactions.
