Abstract

original image

On the ball: Charge transfer occurs readily in tightly interacting complexes formed from π-extended tetrathiafulvalenes, which act as pincerlike receptors, and C60 in a variety of solvents upon photoexcitation (see picture; PET=photoelectron transfer). It should be feasible to construct simple photovoltaic devices from systems based on similar recognition motifs.
