Abstract

Fluorescence of zinc porphyrin in zinc porphyrin-C₆₀ dyads is enhanced by applying an electric field (F) due to a field-induced deceleration of the electron transfer rate from the singlet excited state of zinc porphyrin to C₆₀ in the Marcus top region. Free-base porphyrin-C₆₀ dyads exhibit the opposite electric field effect, since the electron transfer from the singlet excited state of free-base porphyrin to C₆₀ is in the Marcus normal region far from the top.
