【 摘 要 】

New hybrid inorgano�?�organic materials were synthesized by anchoring organic moieties, ortho chlorophenol and para chlorophenol onto metal (IV) tungstates viz. tin tungstate (SnW), titanium tungstate (TiW) and zirconium tungstate (ZW) to give SnWoCP, SnWpCP, TiWoCP, TiWpCP, ZWoCP and ZWpCP, respectively. The materials were characterized for elemental analysis, thermal analysis (TGA, DSC), X-ray analysis and FTIR spectroscopy. Chemical resistivity of these materials were assessed in several acidic, basic and organic media. Further, the study of transport properties of these materials has been explored by measuring proton conductivity at different temperatures in the range 30�??175°C using HP4192A impedance analyser over a frequency range 5 Hz�??13 MHz at a signal level below 1 V. Based on the specific conductance data and Arrhenius plots, a suitable mechanism was proposed and conductance performance of derivatized and nonderivatized materials compared.
