Photophysical properties and photoinduced electron transfer between [60]fullerene-containing cyclic sulphoxide C60-C6H8SO] and tetrathiafulvalene TTF by laser flash photolysis

Photoinduced electron transfer (PEr) Processes between C-60-C6H8SO and Tetrathiafuvalene (TIF) have been studied by nanosecond laser photolysis. Quantani yields (Phi(et)) and rate constants of electron transfer (k(et)) from TIF to excited triplet state of [60] fallerene-containing cyclic sulphoxide in benzonitrile (BN) have been evaluated by observing the transient absorption bands in the NIR region. With the decay of excited triplet state of [60]fullerene-containing cyclic sulphoxide, the rise of radical anion of [60]fullerene-containing cyclic sulphoxide is observed.
