| Abstract: | The covalent linkage of two [60]fullerene cores to a tetrathiafulvalene (TTF) donor affords a soluble and photoactive C(60)-TTF-C(60) triad. Spectroscopic and photophysical characterization of the C(60)-TTF-C(60) 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 C(60), prevails, yielding a long-lived charge separated radical pair. |
