Low-Melting Ionic Solids: Versatile Materials for Ion-Sensing Devices

Abstract

Ionic liquids that melt slightly above room temperature (and may be called low-melting ionic solids, LMISs) were used as sensing materials for the detection of ions in aqueous solutions. A simple procedure based on the consecutive melting and further solidification of the LMISs was applied to prepare solid-contact ion-sensitive electrodes. A potentiometric response toward a number of anions was observed, and the possibility of altering the selectivity by incorporating additional ionophores into the LMIS matrix was demonstrated.

Application of Room Temperature Ionic Liquids in Electrochemical Sensors and Biosensors

“…In 2007, Kakiuchi et al have also introduced a new solid-state reference electrode (Kakiuchi et al, 2007). A new type of Ag/AgCl reference electrode is consists of a Ag/AgCl electrode coated with a AgCl-saturated with a hydrophobic ionic liquid ionic liquid, 1-methyl-3-octylimidazolium bis ( There is another report in 2009 (Chernyshov et al 2009) in which ILs that melt slightly above room temperature (and may be called low-melting ionic solids, LMISs) were used as sensing materials for the detection of ions in aqueous solutions. In this work, Chernyshov et al used a simple method to prepare solid-contact ion-sensitive electrodes based on the consecutive melting and further solidification of the LMISs.…”

Halogen-free imidazolium/ammonium-bis(salicylato)borate ionic liquids as high performance lubricant additives

“…First, the lithium salt of bis(salicylato)borate was prepared by mixing salicylic acid (2.762 g, 20 mmol) in an aqueous solution of lithium carbonate (0.734 g, 10 mmol) and boric acid (0.619 g, 10 mmol). 21 The solution was heated at 60 C for 2 hours under continuous stirring. Then tetrabutylammonium bromide (10 mmol) was added to this solution and heated for a further 2 hours.…”

Properties and Customization of Sensor Materials for Biomedical Applications

“…An attractive advantage of ILs is the ability to use them to tailor or tune the properties of a material, such as the solvation environment that determines ion extraction and complexation equilibria within a membrane (85,119). It may be that ILs will replace conventional ion exchangers (119)(120)(121)(122), plasticizers, or even the ionophore in ISEs, but this area seems still in its infancy and only a few examples have been published in the literature (119,120,123,124).…”
