Abstract
Since 2000, ionic liquids are used for electrode modification. When these ionic liquid modified electrodes are immersed into aqueous solution, a well defined ionic liquid | aqueous electrolyte interface is formed. Here, the papers reporting on ion transfer across this interface are reviewed. This process is generated either by the electrochemical redox reaction within the ionic liquid deposit or it results from selective partitioning between the ionic liquid and the aqueous phase. The papers reporting an accumulation of the redox active ions into a thin film of covalently bonded ionic liquid deposited on the electrode surface are also reviewed.
