Abstract
The covalent linkage of two [60]fullerene cores to a tetrathiafulvalene (TTF) donor affords a soluble and photoactive C60−TTF−C60 triad. Spectroscopic and photophysical characterization of the C60−TTF−C60 triad are given. Although the cyclic voltammetry measurements reveal no notable interaction between the chromophores in the ground state, photophysical data show that in the excited state an intramolecular electron transfer, evolving from the TTF donor to the singlet state of C60, prevails, yielding a long-lived charge separated radical pair.Keywords
