| Abstract
| - This paper reports the preparation and characteristic property of a new nanocomposite gold cluster withfullerene as a carbon nanocluster, C60−Au nanoparticles, together with the first account of electrochemicalcomparison of the C60−Au nanoparticle films and the self-assembled monolayers of C60-thiol 1 on goldelectrodes. Octanethiol-stabilized gold nanoparticles were treated with a fullerene C60-terminated alkanethiol(1) to give new fullerenethiol-functionalized gold nanoparticles (C60−Au nanoparticles) of 2 nm diameterwith a very narrow size distribution. Immersion of a gold electrode in a solution of C60−Au nanoparticlesdeposited the colloid films of them on the electrode surface which showed two distinct reversible reduction/oxidation waves and significant electrochemical stability. The C60−Au nanoparticle films were firmlyimmobilized on the planar electrode by a simple self-assembly method without use of terminal ligand likebifunctional aminosiloxane or mercaptosiloxane. The electrochemical responses for the C60−Au nanoparticlefilms and self-assembled monolayers of C60-thiol 1 adsorbed on gold electrodes are significantly different.
