Charge-transfer in a π-stacked fullerene porphyrin dyad: evidence for back electron transfer in the ‘Marcus-inverted’ region
Abstract
The ‘Marcus-inverted’ region for BET in a π–π 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 charge-separated state
