Binding of a porphyrin carboxylate anion () to tetrathiafulvalene calix[4]pyrrole (TTF-C4P) results in electron transfer from TTF-C4P to Li(+)@C60 to produce the charge-separated state (1/TTF-C4P˙(+)/Li(+)@C60˙(-)) in benzonitrile. Upon photoexcitation of , photoinduced electron transfer from the triplet excited state of to TTF-C4P˙(+) occurs to produce the higher energy charge-separated state (˙(+)/TTF-C4P/Li(+)@C60˙(-)), which decays to the ground state with a lifetime of 4.8 μs.
卟啉羧酸根阴离子（）与四硫富瓦烯杯[4]吡咯（TTF-C4P）结合，导致电子从TTF-C4P转移至Li(+)@C60，从而在苯甲腈中产生电荷分离态（1/TTF-C4P˙(+)/Li(+)@C60˙(-)）。在对进行光激发时，会发生从的三重激发态到TTF-C4P˙(+)的光诱导电子转移，以产生更高能量的电荷分离态（˙(+)/TTF-C4P/Li(+)@C60˙(-)），该态以4.8微秒的寿命衰减至基态。
