Dm. Guldi et al., Charge-transfer in a pi-stacked fullerene porphyrin dyad: evidence for back electron transfer in the 'Marcus-inverted' region, CHEM COMMUN, (5), 2000, pp. 373-374
The 'Marcus-inverted' region for BET in a pi-pi stacked fullerene-porphyrin
dyad was determined based on (i) the photoactivation of an intramolecular
ET in a variety of solvents and (ii) the formation of a highly energetic ch
arge-separated state.
