Abstract
Binding of a porphyrin carboxylate anion (1) to tetrathiafulvalene calix[4]pyrrole (TTF-C4P) results in electron transfer from TTF-C4P to Li+@C-60 to produce the charge-separated state (1/TTF-C4P(center dot+)/Li+@C-60(center dot-)) in benzonitrile. Upon photoexcitation of 1, photoinduced electron transfer from the triplet excited state of 1 to TTF-C4P(center dot+) occurs to produce the higher energy charge-separated state (1(center dot+)/TTF-C4P/Li+@C-60(center dot-)), which decays to the ground state with a lifetime of 4.8 mu s.
