Abstract
Anodic oxidation of Co, Ni, Cu, Zn, Cd and Sn metals in an anhydrous acetone solution of poly(azomethinethiosemicarbazone) (PATS) yields the PATS–metal complexes. Chemical and thermal analyses as well as FTIR and electronic spectral data are presented to confirm the formulation of the isolated materials. The spectral data show that the ligand polymer is coordinated to the metal ions via the thiol sulfur atom and the nitrogen of the azomethine group. Thermogravimetric measurements (TGA) and differential thermal analyses (DTA) were used to obtain the energy of decomposition of PATS and its metal polymer complexes. The DC electrical conductivity measurements of PATS and the polymer complexes as annealed and 5% iodine doped forms were measured in the range 300–500 K. The products gave electrical conductivities in the semi-conducting region that increased with temperature.
