Design and Synthesis of High-Performance Planar Explosives and Solid Propellants with Tetrazole Moieties

A straightforward synthetic strategy for newly designed nitrogen-rich planar explosives and solid propellants is reported. These materials exhibit high densities (1.69–1.95 g cm–3), high positive enthalpies of formation (approaching 1149.21 kJ mol–1), promising energetic properties (P = 26.36–33.78 GPa, D = 8258–9518 m s–1), acceptable thermal stabilities (Td = 132–277 °C), good sensitivities (IS = 4–40 J, FS = 60–360 N) and excellent propulsive performance (Isp = 176.80–253.06 s).
