Three electrodes and a cage: an account of electrochemical research on C60, C70 and their derivatives

An overview of the electrochemistry of C60, C70 and higher fullerenes, and of their derivatives and relatives is given together with highlights on possible future studies and applications. A general introduction gives the idea of the size and importance of this field that embraces classic solution and surface electrochemistry, materials chemistry, interlocked molecular architectures, biosensors and solar-energy conversion. A description of the general electrochemical behaviour for several fullerene derivatives is given together with insights on possible applications.
