Viscosity and Ionic Conductivity of Imidazolium based Ionic Liquids bearing Triiodide Anion

In the electrolyte application for dye sensitized solar cells, utilization of ionic liquids is getting highlights to replace volatile organic solvent thanks their low volatility, thermal and electrochemical stability. The iodide/triiodide redox preferred choice this application, hence numerous iodide-based have been explored reported. On contrary, transport properties triiodide based liquid often lack reporting despite having an equal influence on overall viscosity conductivity electrolyte. study, three alkylimidazolium were synthesized from respective iodide precursors physicochemical are 1 H NMR analysis showed a slight shifting position resonances as compared due less electronegativity nature anion. formation triiodide-based imidazolium ILs dramatically altered in which obtained high conductivity.
