Abstract

New porphyrins having different functionalizations at meso-position (A3B type) and their cobalt, nickel, copper and zinc complexes were synthesized by the reaction of unsymmetrical porphyrins with metal acetates. The synthesized metalloporphyrins were characterized by UV, IR, NMR and Mass spectra. The copper complexes of 1c and 3c were further studied by ESR spectra and magnetic measurements for complexes (1a, 1c and 3c ). Similarly the zinc complexes of 1d and 3d studied by fluorescence spectra
