文摘
A new super heat-resistant explosive, potassium 4-(5-amino-3-nitro-1H-1,2,4-triazol-1-yl)-3,5-dinitropyrazole (KCPT, 1), featuring a three-dimensional (3D) energetic metal–organic framework (MOF) was synthesized and fully characterized. The new 3D MOF was found to be extremely heat-resistant, having a high decomposition temperature of 323 °C. In addition, KCPT exhibits the best calculated detonation performance (vD=8457 m s−1, p=32.5 GPa) among the reported super heat-resistant explosives or energetic potassium salts while retaining a suitable impact sensitivity of 7.5 J, which makes it one of the most promising heat-resistant explosives.
