title: Carbon-based ionogels: tuning the properties of the ionic liquid via carbon-ionic liquid interaction.
abstract: The behavior of two ionic liquids (ILs), 1-ethyl-3-methylimidazolium dicyanamide [Emim][DCA] and 1-ethyl-3-methylimidazolium triflate [Emim][TfO], in (meso)porous carbonaceous hosts was investigated. Prior to IL incorporation into the host, the carbon matrix was thermally annealed between 180 and 900 °C to control carbon condensation and surface chemistry. The resulting materials have an increasing "graphitic" carbon character with increasing treatment temperature, reflected in a modified behavior of the ILs when impregnated into the carbon host. The two ILs show significant changes in the thermal behavior as measured from differential scanning calorimetry; these changes can be assigned to anion-π interaction between the IL anions and the pore wall surfaces of these flexible carbonaceous support materials.
