摘要

Several 5, 15-diarylporphyrin derivatives containing viologen units as an electron acceptor for ultrafast intramolecular electron transfer have been synthesized. The fluorescence of the porphyrin–viologen linked systems was appreciably quenched by the attached viologens. In accordance with this, the formation of a charge-separated state was observed upon excitation with a femtosecond (fs) laser at 400 nm. The rate of electron transfer and back ...
