The formation of water-soluble metalloporphyrin heterodimers from Fe ( III ), Cu ( II ) and Ni ( II ) complexes of 5,10,15,20-tetrakis(4-carboxyphenyl) porphyrin and 5,10,15,20-tetrakis(4-N-methylpyridyl)porphyrin has been investigated using UV-vis, IR and electron paramagnetic resonance spectra. Absorption and IR spectra confirmed the formation of dimers and electron paramagnetic resonance spectra showed evidence for the metal-metal interactions in the dimers.
