Spectral investigations of some bis-linked TTFs to [60]fullerene

Extended spectral investigations of the bis-linked tetrathiafulvalene-derived donors (TTFs) to [60]fullerene were performed. From UV-VIS-NIR-IR spectra it is stated that charge distribution on C 60 moiety and TTFs substituents is disturbed after the adduct formation. In the IR spectra of double-substituted C 60 molecules, a particularly strong resonant effect was observed. The temperature dependence of the spectra has been analyzed.
