Energetic ionic liquids with good thermal stabilities, relatively high densities, and high, positive heats of formation are described. Quaternization of azidoalkyl-substituted 1,2,4-triazoles with 4,5-dinitroimidazole or 5-nitrotetrazole (see Figure) result in room-temperature liquids that may be useful in energetic materials/propellant applications.
