A series of conjugated anthryl-oligothienyl-porphyrins in which the oligothiophene is terminally linked to the 5-position of a porphyrin and to the 9-position of anthracene has been synthesized, and photoexcited-state properties have been studied by steady-state fluorescence spectra, fluorescence excitation spectra and picosecond time-resolved fluorescence measurements. Due to the spectral position of the anthracene and the porphyrin absorption bands a selective excitation of both end groups is possible, which is demonstrated by the UV-visible absorption spectra. Selective excitation of the anthryl end group leads to a quantitative intramolecular energy transfer to the porphyrin end group in the subpicosecond time scale. The mechanism is discussed in terms of existing theories (Forster/Dexter, superexchange, and intramolecular relaxation).
