Rates and energetics of intramolecular electron transfer processes in conjugated metallofullerenes.

In this paper, we report on the design, redox potentials, excited state energies and radical ion pair state energies in electron donor-acceptor conjugates comprising the electron-donating π-extended tetrathiafulvalene and several electron-accepting fullerenes. To this end, we contrast an empty fullerene, that is, C₆₀, with two endohedral metallofullerenes, that is, open-shell La@C₈₂ and closed-shell La₂@C₈₀, in terms of charge separation and charge recombination dynamics.
