Melt-cast explosives are the most widely used energetic materials in military composite explosives, researchers have been unremittingly exploring high-energy and insensitive melt-cast explosives. In this work, a series of dinitrophenyl-oxadiazole compounds were designed prepared. These an ideal low melting point (80–97 °C), good detonation performance (detonation velocity D = 6455–6971 m/s, pressure P 18–19 GPa) extreme nature (impact sensitivity ≥60 J, friction >360 N). All these well characterized by nuclear magnetic resonance, fourier transform infrared spectroscopy, elemental analysis. Compounds 2, 3 unambiguously confirmed X-ray single crystal diffraction As result, their overall properties superior to traditional trinitrotoluene (TNT) dinitroanisole (DNAN) which may excellent potential applications

Nitrogen heterocyclic scaffolds retain their leading position as valuable building blocks in material science, particularly for the design of small-molecule energetic materials. However, search more balanced combinations directly linked cores is far from being exhausted and aims to reach ideally high-energy substances. Herein, we present synthetic route novel pyrazole-furoxan framework enriched with nitro groups demonstrate a promising set properties, viz., good thermal stability, acceptable mechanical sensitivity, high detonation performance. In-depth crystal analysis showed that isomers having lower-impact sensitivity values both types regioisomeric pairs are those exocyclic furoxan oxygen atom closer pyrazole ring. Owing favorable combination densities (1.83-1.93 g cm

The evolution of energetic materials science presents new challenging tasks associated with the creation advanced technologies for sustainable development future. In this work, a set heat-resistant high-energy incorporating polynitrophenyl-1,2,5-oxadiazole scaffold enriched azo/azoxy moieties have been designed and synthesized. Due to smart combination explosophoric groups 1,2,5-oxadiazole rings, prepared substances excellent thermal stability (up 300 °C), good densities 1.75 g cm–3), high enthalpies formation (340–538 kJ mol–1), combined nitrogen–oxygen content (63–68%). In-depth structural analysis revealed presence strong intra- intermolecular hydrogen bonds in aminodinitrophenyl derivatives, which small deviation electrostatic potential values explains low mechanical sensitivity these materials. At same time, trinitrophenyl-1,2,5-oxadiazoles three adjacent non-coplanar nitro demonstrated higher impact, albeit retaining complete insensitivity friction. overall performance thus exceeds that known explosive hexanitrostilbene. Therefore, newly synthesized family polynitrophenyl-1,2,5-oxadiazoles provides fruitful foundation
