Alteration of the electrochemistry of fullerene C₆₀ in the presence of dioxygen: Formation of a redox‐active polymeric film

A new route to the formation of an electrochemically active film that contains fullerene units is reported. The method involves the reduction of C₆₀ to its dianion in the presence of dioxygen and produces a film (see Figure) that is similar, but not identical to films prepared by the electrochemical reduction of C₆₀O. This new method of fullerence polymerization therefore avoids the need for the tedious preparation and purification of C₆₀O. fig.magnified image
