(2)H and (19)F solid-state NMR studies of the ionic liquid [C(2)Py][BTA]-d(10) confined in mesoporous silica materials.

Ionic liquids confined in porous materials are important solvents which allow a simple heterogenization of homogenous liquids. The perdeuterated ionic liquid N-ethylpyridinium-bis(trifluoromethanesulfonyl)amide ([C(2)Py][BTA]-d(10)) was prepared and its bulk phase behavior was studied by differential scanning calorimetry (DSC) and temperature-resolved (2)H and (19)F solid-state NMR spectroscopy. Its bulk properties were compared to [C(2)Py][BTA]-d(10) confined in a mesoporous silica support material as model material usable in SILP catalysts.
