摘要

Photoinduced electron transfer (PET) processes between C60-C6H8SO and Tetrathiafulvalene (TTF) have been studied by nanosecond laser photolysis. Quantum yields (φet) and rate constants of electron transfer (ket) from TTF to excited triplet state of [ 60 ] fullerene-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.
