The redox reactions of C60 fullerene incorporated into a cast film of an artificial lipid (tri-n-dodecylmethylammonium bromide, 3C12N+Br-) on a boron-doped p-type semiconductive diamond electrode were investigated in an aqueous medium. The electrode showed one quasi-reversible and one sigmoidal wave in the cyclic voltammogram. In contrast, three quasi-reversible waves were observed when using a basal-plane pyrolytic graphite electrode. The redox mechanism of C60 in the 3C12N+Br- film on the diamond electrode is explained using an electron energy diagram. The significance of the surface states in the hole transfer processes from the diamond electrode to C60 in the lipid film is discussed.
