Abstract

Fullerenes exhibit rich redox activity and are able to accommodate up to 6 surplus electrons or give away 1–2 electrons in solution. EMFs inherit this property from empty fullerenes, and also add a new dimension to the redox behavior because endohedral clusters can exhibit their own redox activity despite their shielding by the carbon cage. This chapter provides a systematic overview of electrochemical properties of different classes of endohedral metallofullerenes. In particular, the balance between fullerene- and cluster-based redox activity in complex endohedral metallofullerenes is discussed using frontier molecular orbitals as a guide.
