(Equation Presented) Por-nT-C60 (x = 1-3) A series of porphyrin-oligothiophene-fullerene triads containing quaterthiophene, octithiophene, and dodecithiophene spacers has been synthesized. The fluorescence of the porphyrin chromophore in benzonitrile is efficiently quenched by electron transfer to the fullerene moiety. This process shows a weak distance dependence of the oligothiophene spacer with an attenuation factor β = 0.11 Å-1.
