Electrical properties of some cobalt phthalocyanines

The conductivity and dielectric properties of monomeric and polymeric cobalt phthalocyanine (CoPc) prepared under different conditions are discussed. All CoPc derivatives studied show very high specific conductivity as compared to microscopic-grade CoPc. The dielectric constants are frequency dependent, with the highest response occurring at the lower frequencies of the applied electric field, indicative of nomadic polarization. The dielectric constant increases strongly with temperature.<
