In order to study the properties of new energetic compounds formed by introducing nitroazoles into 2,4,6‐trinitrobezene, the density, heat of formation and detonation properties of 36 nitro‐1‐(2,4,6‐trinitrobenzene)‐1H‐azoles energetic compounds are studied by density functional theory, and their stability and melting point are predicted. The results show that most of target compounds have good detonation properties and stability. And it is found that nitro‐1‐(2,4,6‐Trinitrophenyl)‐1H‐pyrrole compounds and nitro‐1‐(2,4,6‐trinitrop‐enyl)‐1H‐Imidazole compounds have good thermal stability, and their weakest bond is CNO2 bond, the bond dissociation energy of the weakest bond is 222–238 kJ mol−1 and close to 2,4,6‐trinitrotoluene (235 kJ mol−1). The weakest bond of the other compounds may be the CNO2 bond or the NN bond, and the strength of the NN bond is related to the nitro group on azole ring.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
