Synthesis and Properties of Three Sulfur-Containing Porphyrins, One Water-Soluble

Abstract

Three new porphyrins with sulfur functional groups, one of which is water-soluble, have been prepared. Their UV-visible absorption, fluorescence emission, and 1H NMR spectra as well as their copper(2+) insertion kinetics, pK3 values and first and second reduction potentials determined. For the water soluble porphyrin, its binding with human serum albumin (HSA) determined.
