Dislike water: Using a combined experimental and theoretical approach, we show that ionic liquids can be more hydrophobic than the organic solvents (see picture), such as chloromethane or benzene. This is quite surprising for a liquid consisting solely of ions which are expected to interact rigorously with water. It is demonstrated that the stretching frequencies of dissolved water molecules are sensitive probes for the hydrophobicity of ion surfaces.
