Paper Abstract

Zn-Tetraphenylporphyrin-(SO-3)4 forms two types of complexes with a covalently linked viologenanthraquinone (VA) compound both in H2O and methanol. In both complexes fluorescence quenching occurs on a time scale < 10 ps and 0.5 ns, respectively, and its tentatively assigned to photo-induced electron transfer from porphyrin to VA.
