Abstract

The electrochemical behavior and electrical conductivity of C60 thin films were studied in acetonitrile containing M(bpy)32+ (M Fe, Ni, Ru or Os; bpy 2,2′-bipyridine). Cyclic voltammetry of C60 films showed stable reduction-reoxidation waves. In situ conductivity measurements indicated that an enhanced conductivity (on the order of 10-2 S cm-) appeared reversibly on electrochemical reduction accompanied by doping of M(bpy)32+ ions into the C60 films. The electrochemical reduction also induced some structural change.
