Abstract: Fluorescence properties of meso-tetrafurylporphyrins with N-4, N3S and N2S2 porphyrin cores are studied by both steady-state and time-resolved fluorescence techniques and compared with the corresponding meso-tetraarylporphyrins. The study shows that the replacement of six-membered aryl groups with five-membered furyl groups at meso-positions alter the fluorescence properties considerably, as reflected in the large red shifts and broadening of fluorescence bands with reduction in quantum yields and singlet excited-state lifetimes. However, zinc(II) derivatives of meso-tetrafurylporphyrin and meso-tetraarylporphyrin did not show significant differences in their emission properties.
