## 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
Fluorescence quenching in chlorophyll-a induced by radiationless intermolecular singlet-triplet energy transfer is reported. The process may have important photochemical implications. A two-laser excitation procedure is employed to observe the quenching. The method complements fluorescence spectrosc
