✦ Synopsis

An iron-phthalocyanine polymer has been characterized by infrared spectroscopy, X-ray diffraction and Mossbauer spectroscopy. The electrical properties of resistivity, dielectric constant and the thermally stimulated depolarization effect have been investigated in the temperature range 30-240°C. The depolarization of thermoelectret shows two current peaks at about 176°C and 200°C. The unpolarized sample also displays a pyroelectric current on heating, indicating the possibility of ferroelectric polarization. A temperature-dependent measurement of the dielectric constant exhibits a dielectric maximum around 180°C which is likely due to electret current peaks. The results have been compared with a monomer of iron-phthalocyanine and interpretations are made in terms of the highly delocalized n-electron system of the phthalocyanine macrocycle being further extended by polymerization.
