偶氮桥连富氮杂环含能化合物的合成及性能研究进展

The azo functionality is not only a bridging block, but also can generally increase the density and heat of formation of energetic nitrogen‑rich heterocycles. Therefore, building new energetic materials through the bridging method has gradually become a research hotspot in this field. This article reviewed synthesis method, physical and chemical properties and detonation properties of azo‑bridged nitrogen‑rich heterocycles focusing on azoles and azines from C-NH₂ and N-NH₂ oxidative couplings. This review will provide some references for the research and development of new azo‑bridged nitrogen‑rich heterocycles.
