Iodide-based ionic liquids viscosity

In a very unique approach cyano substituted triazolate based ionic liquids were prep>ared by exchanging the anions in common ionic liquids such as [emim][l], [empyrr][I] or [epy][T with silver 4,5-dicyano-triazolate in water. Here the triazolate ring serves as a counter-anion with delocalized negative charge, and results in a ditninished cation-anion interaction due to its decreased charge density. Hence, there is a decrease in the viscosity of the resulting ionic liquids as compared to those with iodide counter-ions (Kitaoka, Nobuoka et al. 2010). [Pg.18]

Room temperature molten salts based on imidazolium iodides have revealed very attractive stability features (Kubo, 2002 Wang, 2003). Despite their high viscosity impressive overall conversion efficiencies exceeding 6% have been obtained so far. This has been attributed to a Grothus mechanism which increases the diffusion coefficient of the triiodide ions in the melt and to a very effective mode of charge screening which is operative in this ionic liquids. [Pg.1495]
