velocities) of the materials were ascertained with EXPLO5 v6.02. The results suggest that azofurazan derivatives exhibit excellent detonation properties (detonation pressures of 21.8–46.1 GPa and detonation velocities of 6602–10 114 m s−1) and relatively lowimpact and frictionsensitivities (6.0–80 J and 80–360 N, respectively). In particular, they have low electrostatic spark sensitivities (0.13–1.05 J)

order to develop high energy density materials, compounds 3, 4 and 6 were synthesized by the simple nitration, oxidation and oxidation coupling reaction of compound 2. In addition, six energetic salts based on 3 and 4 were synthesized, respectively. Compounds 2–12 were characterized by IR spectroscopy, multinuclear NMR spectroscopy and elemental analysis. The structures of compounds 2, 4 and 7 were
