Heat-resistant explosives play an irreplaceable role in aerospace and deep well drilling applications. Sodium (1) potassium (2) 3,5-dinitro-4-hydropyrazolate salts were prepared featuring three-dimensional energetic metal–organic frameworks (3D EMOFs). As comparative examples, sodium (3) (4) 3,5-dinitro-4-amino-pyrazolate also prepared. Crystal structure analyses show that compared with 3 4, the shorter more coordinating bonds of 1 2 give rise to densities up 2.13 2.22 g cm–3, respectively, their decomposition temperatures as high 395 376 °C, respectively. In addition, sensitivity mechanical stimulation detonation performance 1–4 studied compared. This super-thermal-stability suggests promising super-heat-resistant explosives.

Abstract Owing to its simple preparation and high oxygen content, nitroformate [ − C(NO 2 ) 3 , NF] is an extremely attractive oxidant component for propellants explosives. However, the poor thermostability of NF-based derivatives has been unconquerable barrier more than 150 years, thus hindering application. In this study, first example a nitrogen-rich hydrogen-bonded organic framework (HOF-NF) designed constructed through self-assembly in energetic materials, which NF anions are trapped pores resulting via dual force ionic hydrogen bonds from strengthened framework. These factors lead decomposition temperature HOF-NF moiety being 200 °C, exceeds challenge thermal stability over 180 °C time among compounds. A large number compounds with stabilities excellent properties can be synthesized on basis work.
