The parent platinum phthalocyanine (PtPc) and its derivatives with tetranitro (PtTNPc) and tetramine (PtTAPc) on the peripheral benzene were synthesized in the pure state for the first time by microwave irradiation. These complexes were characterized using physico-chemical methods like elemental, electronic absorption, IR spectral, magnetic susceptibility, thermogravimetry and X-ray powder diffraction studies. Kinetic and thermodynamic parameters associated with the thermal decomposition were calculated using the thermogravimetric analytical data. Electrical conductivity studies were carried out using the two-probe technique in the temperature range 298-473 K for each complex to study the effect of the donor and acceptor substituents on the platinum phthalocyanine macrocycle. The electrical conductivities observed at room temperature are in the order PtTAPc > PtTNPc > PtPc. The improvement in the intrinsic electrical conductivity of PtTAPc is due to the electron donating amine substituents which are expected to facilitate greater intermolecular contact and increase interactions, providing a greater pathway for charge carriers.
