Intramolecular photoinduced electron transfer reaction of a series of fixed distance triads consisting of free-base porphyrin, zinc porphyrin, and quinone or pyromellitimide have been investigated by means of steady-state fluorescence spectroscopy, picosecond time-resolved fluorescence spectroscopy,
Intramolecular transfer processes in porphyrin-phthalocyanine heterodimers covalently linked by an oxygen atom (restricted conformation) and/or by a flexible chain of variable length were investigated. Fluorescence spectroscopy shows that singlet-singlet energy transfer from the porphyrin to the pht
