摘要

在这项研究中，我们合成了一系列新的含硝胺、叠氮化物和肼官能团的融合环偶氮桥化合物。新合成的化合物具有良好的能量性能，包括良好的密度（1.71 ~ 1.76 g cm-3），良好的爆轰速度（7203 ~ 8104 m s-1），可控的冲击（2.5 ~ 40 J）和摩擦灵敏度（120 ~ 360 N），热稳定性范围为128℃~ 300℃。值得注意的是，化合物4作为一种耐热炸药表现出优异的热稳定性（300°C），而化合物7作为一种极有前途的无铅初级炸药，最低底火装药量仅为40毫克。

Fused Azo-Bridged Triazolo-Pyridazine-Derived Energetic Materials

In this study, we synthesized a series of novel fused-ring azo-bridged compounds incorporating nitramine, azide, and hydrazine functional groups. The newly synthesized compounds exhibited promising energetic properties, including good densities (1.71–1.76 g cm^–3), good detonation velocities (7203–8104 m s^–1), controlled impact (2.5–40 J), and friction sensitivities (120–360 N), and the thermal stability ranged from 128 °C to 300 °C. Notably, compound 4 demonstrated exceptional thermal stability (300 °C) as an heat-resistant explosive, while compound 7 emerged as a highly promising lead-free primary explosive with an ultralow minimum primer charge of just 40 mg.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
