The reduction of tetrachloroaurate or potassium tetrachloropalladate with sodium borohydride in the presence of terthienyldecanethiol gave the terthiophene-modified gold or palladium nanoparticles which showed the small core (1.8nm for TTP-Au or 1.7nm for TTP-Pd) with narrow size distribution and remarkably high stability. The redoxactive multifunctional gold nanoparticles (C60-TTP-Au : particle size 1.8nm) containing C60-fullerene and terthienyl groups were prepared by the ligand-exchange reaction of TTP-Au with a C60-substituted decanethiol. Their novel polythiophene-metal nanoparticle composite films were deposited on metal electrodes by electropolymerization. The poly (C60-TTP-Au) films modified metal electrodes show two distinct reversible redox peaks due to the C60 groups and are considerably stable in organic solvents under repeated potential cycling.
