In this study, a new class of dicyanamide-based ionic liquids containing mono and dicationic counterparts was synthesized and characterized. Results demonstrate that the physical properties of these salts, including thermal stability, melting point, density and viscosity, are highly dependent on the structure of cation and type of anion. It was observed that the thermal stability of dicationic ionic liquids is higher for the monocationic ones. Furthermore, droplet tests were used to investigate the hypergolic properties of these ionic liquids. All of the synthesized compounds showed hypergolic activity upon contact with white fuming nitric acid, suggesting that some may have potential for application as bipropellants or energetic additives.

Nine 1-allyl-3-alkylimidazolium ([ACnIm]) or 1-vinyl-3-alkylimidazolium ([VCnIm]) dicyanamides (DCA) were prepared and characterized, and their physicochemical properties were studied in detail. Except for [AVIm]DCA and [AC4Im]DCA, the other dicyanamides with hexyl or longer alkyl chains on the cation exhibited the characteristic of hydrophobicity. Among them, [AC8Im]DCA and [AC10Im]DCA were found to possess similar densities to water, i.e. 1.007 g cm-3 and 0.988 g cm-3 at 25 °C, respectively. Interestingly, a reversible phase reversion of a [AC8Im]DCA/H2O mixture was observed as the temperature varied. These environmentally-friendly liquid materials have potential applications as precursors for syntheses of conducting polymeric materials.
