Abstract
BECAUSE of the strong long range forces acting between the molecules, molten salts constitute a highly distinctive class of liquids. Up to now, however, the variety of stable ionic melts studied has been largely confined to the simplest ions, such as inert gas type halides, nitrates, and network forming oxides and fluorides. Through the establishment of procedures for achieving chemical stability in molten salts with organic anions1,2, the variety of these ionic melts available for investigation and use is potentially greatly increased. Distinctive microstructures and unusual properties might be expected for at least some of these liquids. We illustrate these possibilities here with new observations on liquid crystals, stable over a wide interval of temperatures, formed by melts of sodium isovalerate and related salts. This group of substances differs in several ways from well known classes of liquid crystals, which include chiefly rod-shaped molecules, with long rigid parts3.
