Among energetic materials, there is a significant challenge facing researchers: to seek an optimal balance between detonation performance and molecular stability. By introducing an azo1,2,4-oxadiazole backbone and low-sensitivity C-NO₂ moieties, a promising energetic molecule, 1,2-bis(3-nitro-1,2,4-oxadiazol-5-yl)diazene (4) was prepared through three-step reaction and well-characterized by IR and multinuclear NMR spectroscopy, DSC measurement, elemental analysis, and single-crystal X-ray diffraction. It shows high thermal stability (T_d=260 °C), good mechanical sensitivity (IS: 21 J, FS: 220 N), and superior detonation performance (D: 9336 m s⁻¹, P: 37.7 GPa). The combination of advanced performance and desirable safety as well as the simple reaction process make it highly competitive in the field of energetic materials.
