Description
Summary:A new super heat-resistant explosive, potassium 4-(5-amino-3-nitro-1H-1,2,4-triazol-1-yl)-3,5-dini tropyrazole (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 degree C. In addition, KCPT exhibits the best calculated detonation performance (v sub(D)=8457ms super(-1), p=32.5GPa) among the reported super heat-resistant explosives or energetic potassium salts while retaining a suitable impact sensitivity of 7.5J, which makes it one of the most promising heat-resistant explosives. A bigger bang: A new three-dimensional energetic metal-organic framework as super heat-resistant explosive is formed by self-assembly of a multidentate ligand and potassium ion. Potassium 4-(5-amino-3-nitro-1H-1,2,4-triazol-1-yl)-3,5-dini tropyrazole shows superior heat resistance with a high decomposition temperature of 323 degree C and outstanding detonation performance.
