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.
