Abstract A series of functionalized imidazolium and 1, 2, 4-triazolium salts with cyanomethyl, vinyl and propargyl substituents coupled with energetic anions, viz., perchlorate, nitrate, dicyanamide and dinitramide were prepared and characterized by NMR and IR spectroscopy, and elemental analyses. Since some melt< 100 C, they can be classed as ionic liquids. Their densities range between 1.25–1.76 g cm–3. The standard enthalpies of ...
