Unique Molecular Properties of a Paramagnetic Endohedral Metallofullerene La@C82: Its Chemical Reactivities, and Electronic and Magnetic Properties
La@C82 has extensively been investigated as a prototype paramagnetic fullerene because it is the first endohedral metallofullerene which was reported the successful isolation for the first time.  Moreover, it was demonstrated that a family of lanthanum containing fullerenes were produced and that extraction with toluene yielded abundantly La@C82. La@C82 has an electronic structure which is best described as [La]3+[C82]3- with an open-shell electronic character that is a consequence of transferring three electrons from lanthanum to C82 (Scheme). The resulting electron spin imposes a unique chemical reactivity comparable to that of a radical character. The latter is believed to induce magnetism and enhance electron conductivity. In this regard, our group has investigated and revealed unprecedented molecular properties of La@C82.
In this talk, I will present its unique radical reactivity, photo-induced intramolecular electron transfer, and the SAM demonstrating electrochemical switching based on La@C82.
