    Abstract:

    The development of new energetic materials with high energy, low sensitivity, and high thermal stability is always desirable. In this study, a series of tetrazole-linked 4, 8-dihydrodifurazano [3, 4-b, e] pyrazine (DFP) based energetic salts have been synthesized and fully characterized. The as-synthesized energetic salts exhibited excellent comprehensive performances in terms of high decomposition temperature (Td > 260 ℃), low mechanical sensitivity (IS≥20 J and FS≥360 N), and high detonation velocity (D > 8800 m·s-1). Notably, the thermal decomposition temperature of di (aminoguanidinium)-4, 8-di (1H-tetrazol-5-yl)-difurazano [3, 4-b, e] pyrazine (compound 4e) is up to 314 ℃, while its detonation velocity and impact sensitivity are highly desirable with the values of 9005 m·s-1 and 25 J, respectively. Overall, these novel energetic compounds have shown their great-potential as insensitive high-energy-density materials.
