A series of ortho-, meta-and para-substituted zinc porphyrin-pheophorbide dyads were synthesized directly from methyl pheophorbide-a by trans-esterification of ~-keto methyl ester with hydroxymethyl substituted porphyrins. Quantitative energy transfer occurred from the excited zinc porphyrin to the
## 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
