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.
