Raj. Janssen et al., PHOTOINDUCED ABSORPTION-SPECTROSCOPY OF OLIGOTHIOPHENE C-60 MIXTURES IN FILMS AND SOLUTIONS, Synthetic metals, 70(1-3), 1995, pp. 1345-1346
We present spectral evidence for the formation of triplet-state photoe
xcitations in T-7 films and solutions. Introduction of C-60 affects th
e photophysical processes dramatically via electron transfer (film) or
energy transfer (solution) from photoexcited T-7 to C-60.
