Steady-state fluorescence, lifetime measurements and time-resolved absorption spectra of the covalentty linked heterc dimers consisting of pheophorbide and porphyrin revealed rapid ( 1011-10'2 s-' ) and efficient singlet-singlet excitation energy transfer from porphyrin unit to pheophorbide.
Experimental and calculated absorption spectra are compared for four different porphyrin dimers covalently linked by alkyl- or phenyl bridges. The spectra of the corresponding monomers were used as a reference to determine the experimental exciton,ic shift(s) of the absorption spectrum in the Soret
