Description
Summary:•A condensed tetrazole energetic material 3 were synthesized.•Energetic material 3 which exhibits thermal stability (Td(onest)=312 °C) comparable to that of traditional heat-resistant material HNS (Td(onest)=318 °C).•Compound 3 shows lower mechanical sensitivity (IS=40 J, FS=360 J) compared to HNS (IS=5 J, FS=240 J). The synthesis and characterization of a heat-resistant and low mechanical sensitivity fused ring tetrazole compound was presented, utilizing IR, multinuclear NMR spectroscopy, thermal analysis, and elemental analysis. It was further analyzed through single crystal X-ray diffraction. The extensive non-covalent interactions (hydrogen bonding and π-π interactions) confer upon compound 3 excellent thermal stability (Td(onest)=312 °C) and outstanding mechanical stability (IS=40 J, FS=360 N), highlighting its potential as a new heat-resistant and insensitive energetic material for future application.
