Understanding phenomena at the interface is a challenging subject in both experimental and theoretical research. The behavior of ions at the air/water interface is of special interest since it is relevant for many surface chemical reactions. Ionic liquids are liquid organic salts that are generally composed of a bulky hydrophobic cationic partner and a smaller but generally multiatomic and more hydrophilic anionic partner. The propensity of the constituent hydrophobic and hydrophilic ions of ionic liquids for the air/water interface raises many questions regarding the self-assembly of these ions and their interactions with water molecules. How do these ions interact with water. How do hydrogen-bonding networks of water change when ions have strong propensity to the surface. Are wateranion interactions stronger than watercation or water–water interactions. How are those interactions affected at different concentrations of ionic liquids. How does the nature of these cations and anions influence surface properties and orientation of ions at the interface. How do ionic liquids make self assemblies at the interface, and which are the dominant forces for this process. T. his minireview aims to answer these questions.
