Benzimidazole-based low-sensitivity and heat-resistant energetic materials: design and synthesis

A new heat-resistant functional material, 4,6-diamino-5,7-dinitro-1 H -benzo[ d ]imidazole (DADNBI) was prepared. The thermal decomposition temperature of DADNBI is 366 °C, h 50% is 305 cm, and the detonation velocity is 7306 m s −1 .
