Ionic liquids is one of the focal points for HEDM research. HEDM research effort has shifted away from cryogenic/matrix isolation and now is pointing into synthetic endeavors. Ionic liquids have been around a very long time (100 years), and recently they have really taken off. But in this "take off" most researchers are looking for applications in the use of ionic liquids. Few people are looking at ionic liquids for the "why" these materials are low melting and how this unusual class of compounds might be more useful for other applications
