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).
