Description A series of beta-pyrrole and beta-thiophene substituted porphyrins with N2S2 and N3S porphyrin cores were synthesized and characterized. The introduction of substituents at beta-pyrrole and beta-thiophene carbons resulted in significant shifts in H-1 NMR, absorption and fluorescence maxima. These effects were attributed to alteration of the porphyrin ring current caused by substituents at beta-positions. (C) 2004
