Ionic liquids (ILs) are defined as organic salts formed by the combination of bulky organic cations with a wide variety of anions, that are generally liquid at room temperature.1 ILs are made up of large ions that are held together by elec-trostatic interactions. Due to these interactions, the properties of ILs are consi-derably different from those of molecular liquids.2 ILs have been widely ...
