## Abstract Two compounds containing a porphyrin dimer and a perylene tetracarboxylic diimide (PDI) linked by phenyl (**1**) or ethylene groups (**2**) are prepared. The photophysical properties of these two compounds are investigated by steady state electronic absorption and fluorescence spectra a
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
