Abstract

Steady-state fluorescence, lifetime measurements and time-resolved absorption spectra of the covalently linked hetero dimers consisting of pheophorbide and porphyrin revealed rapid (1011-1012s-1) and efficient singlet-singlet excitation energy transfer from porphyrin unit to pheophorbide.
