Optical properties and sensor applications of bimetallic nanostructures of porphyrins

The cationic Cu(II) and Fe(III) complexes of tetra(4-pyridyl)porphyrin [T4PyP]4+ have been combined with the anionic [H4TPPS]2− to obtain bimetallic J-aggregate nanostructures defined by the tendency to form the FeIIIOCuII bridge along with electrostatic interactions.
