Abstract: | Lead (II) phthalocyanine (PbPc); lead (II) tetranitro phthalocyanine (PbTNP) and lead (II) tetraamino phthalocyanine (PbTAP) are synthesized in pure state. These complexes are characterized using elemental analysis, UV-visible, IR-spectroscopy, X-ray crystallography and thermogravimetry. Kinetic and thermodynamic parameters associated with the thermal decomposition were calculated using thermogravimetric data. Electrical conductivity studies are done for all the three complexes using two-probe technique in the temperature range from 30 to 200 °C. The electrical conductivity observed at 30 °C are in the order PbTAP > PbTNP > PbPc. The relevant electrical conductivity data observed are reported. |
