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 (T_d = 132-277 °C), good sensitivities (IS = 4-40 J, FS = 60-360 N) and excellent propulsive performance (Isp = 176.80-253.06 s).
