Abstract
AbstractPolyazomethinethiosemicarbazone (PATS) metal complexes of Ni(II), Co(II), Cu(II), Zn(II), Cd(II) and Hg(II) metal ions were prepared by reacting the polymer ligand (PATS) with the appropriate metal salt in refluxing DMSO. Elemental analyzes 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 bonded to the metal ions via the thiol sulfur atom and coordinated through the nitrogen of azomethine group. The DC electrical conductivity measurements of PATS and its metal complexes were measured in the range 300–500 K in the annealed and 5% iodine doped forms. The products gave electrical conductivity in the semiconducting region that increased by heat. The DC electrical conductivity is interpreted using the band gap theory using solitons, polarons and bipolarons. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
