A novel high-nitrogen compound with an N,N′-azo linkage, 4,4′-azobis(1,2,4-triazole), has been synthesized and well characterized. The solid-state structure was determined by X-ray diffraction. experimentally density enthalpy of formation matched theoretically computed values based on the B3LYP method. DSC result suggests that 4,4′-azobis(1,2,4-triazole) decomposes at a relatively high temperature (313.36 °C). By comparison 3,3′-azobis(1,2,4-triazole), containing C,C′-azo linkage found to...
Energetic polynitro anions, such as dinitramide ion [N(NO2)2–], have attracted significant interest in the field of energetic materials due to their high densities and rich oxygen contents; however, most them usually suffer from low stability. Conveniently stabilizing anions develop new energy well tuning properties still represent challenges. To address these challenges, we herein propose a novel strategy that are encapsulated within cationic metal–organic frameworks (MOFs). We present...
Accurate prediction to the detonation performances of different kinds energetic materials has attracted significant attention in area high energy density (HEDMs). A common approach for estimation CHNO explosives is Kamlet-Jacobs (K-J) equation. However, with development materials, components are no longer restricted elements.

New highly energetic coordination polymers (ECPs), based on the graphene oxide (GO)-copper(II) complex, have been synthesized using 5,5′-azo-1,2,3,4-tetrazole (TEZ) and 4,4′-azo-1,2,4-triazole (ATRZ), as linking ligands between GO-Cu layers. The molecular structures, sensitivity, detonation performances of these ECPs were determined. It was shown that nanomaterials are insensitive thermostable, due to high heat impact dissipation capacity GO sheets. In particular, GO-TEZ-Cu(II) ECP shows low...
