Abstract
Cobalt(III) porphyrins of general formula Co(P)(L) 2 , where P=tetrakis[4-(N-methylpyridiniumyl)]porphine (TMPyP) or tetrakis(4-carboxylatophenyl)porphine (TCPP) and L=amino acid, have been studied in water solution by 1 H NMR spectroscopy. Complexes with the stoichiometry Co(P)(L) 2 are the predominant species above pH 7, whereas at lower pH values Co(P)(L)(H 2 O) species are also present. In the general case, the two amino acid ligands were bound to the cobalt atom through the NH 2 group
