Doping Experiments with μ-(Pyrazine)phthalocyaninatoiron(II)
Phthalocyaninatoiron(II) and -ruthenium(II) compounds [PcML]n (M = Fe, Ru) with different bridging ligands L = 1,4-diisocyano-benzene (1, 4-dib), 1, 4-dicyanobenzene (dcb), 4, 4′-diisocyano-biphenyl (dibph) and 4, 4′-bipyridylacetylene (bpyac), 2, 3, 5, 6-tetramethyldiisocyanobenzene (Me4dib), 2, 3, 5, 6-tetrachlorodiiso-cyanobenzene (Cl4dib) and 1, 3-diisocyanobenzene (1, 3-dib) were reacted with iodine using different doping procedures. All the compounds [PcMLIy]n which were formed were characterized by TG measurements, infrared-, resonance Raman- and 57Fe-Mößbauer spectroscopy /1/. We also report on electrochemical doping experiments with (β-pyrazine)-phthalocyaninatoiron(II) [PcFe(pyz)]n using a variety of different conditions and counterions. It was intended to study a) the influence of various counterions upon the conductivity and stability of the compound [PcFe(pyz)] and b) to investigate if oxidation occurs at the macrocycle or at the central metal atom.
