Abstract  Ionic liquids are an emerging class of materials with a diverse and extraordinary set of properties. Understanding the origins of these properties and how they can be controlled by design to serve valuable practical applications presents a wide array of challenges and opportunities to the chemical physics and physical chemistry community. We highlight here some of the signifcant progress already made and future research directions in this exciting area. J. Chem. Phys. 132, 120901 (2010)
