“…[7] Iodine addition to iodide-based ionic liquids leads to extraordinarily efficient charge transport, vastly exceeding that expected for such viscous systems. [8][9][10][11][12] The origin of this anomalously high charge transport in I /I 3 anion containing melts has been attributed to Grotthuss conduction via the exchange reaction I I 3 I 3 I . [1] The displacement of I and I 3 through this bond-exchange reaction leads to effective charge transfer without mass displacement.…”

“…16,[28][29][30][31][32][33][34][35][36][37][38] In the sensing eld, ionic liquids in contact with a quartz crystal microbalance 39,40 have recently been used to determine organic vapours. The sensing mechanism in this example is based on the fact that the viscosity of the ionic liquid contained in a membrane adhered to a quartz crystal surface decreases signicantly upon dissolution of even a small amount of volatile organic solvent.…”

Applications of voltammetric ion selective electrodes to complex matrices

The practical application of two different voltammetric ion selective electrodes (VISE) to measure ion activity in complex solutions has been explored. 7,7,8, and tetrathiafulvalene (TTF) microcrystals adhered to an electrode surface act as a low selectivity voltammetric ion sensor. Resistance drop effects and pH artifacts were minimised by the addition of an "innocent" supporting electrolyte (buffer) to the analyte solution. In this format, addition of an ionophore to improve selectivity resulted in a reduction in current magnitude, due to competition for the ion. In contrast, voltammetry of a thin film containing a redox active species, electrolyte, ionophore and membrane solvent provides a highly selective ion sensor. Choice of ionophore was shown to affect the upper concentration detection limit. Use of ionic liquids as a combined membrane solvent and electrolyte was demonstrated. Methods to attach both VISE types to low-cost screen-printed electrodes have been explored. Various potential referencing techniques were also investigated. Both the microcrystal and thin film VISEs could be used to determine ion activity in complex solutions, as demonstrated in seawater, beverages, plasma and whole blood. Dissolved oxygen does not need to be removed, as it does not affect the response. However calibration methods are important for sensor accuracy and issues relating to electrode fouling must be addressed.

“…In recent years, room-temperature ionic liquids have also been investigated as potential candidate electrolytes for use in batteries, photoelectrochemical cells, electroplating, and capacitors. [7][8][9][10] The presence of normal organic liquid electrolytes in photoelectrochemical solar cells can result in some practical limitations with sealing, long-term operation, and thermal stability. Hence, ionic liquid electrolytes have been employed as iodine and iodide-based liquid electrolytes to replace organic solvent-based liquid electrolytes in photoelectrochemical solar cells in this study.…”
