Triazoline[4,5][60]fullerenes are strong electron accepters that form with
tetrathiafulvalene (TTF), a novel type of donor-acceptor dyad exhibiting ef
ficient improved electron-transfer dynamics. In particular, a rapid photoin
duced intramolecular electron transfer, forming a charge-separated state, i
s followed by a slow charge recombination to generate the fullerene triplet
excited state in moderate quantum yields.
