Since highly nitrated nitrogen-rich heterocycles are important motifs in high energy density materials, extensive studies for the development of such novel molecules have been underway. A highly energetic moiety, 3-dinitromethyl-5-nitramino-1,2,4-triazole, which consists of a triazole ring, and nitramino and dinitromethyl groups, has been designed and synthesized. By pairing with nitrogen-rich cations, several ionic derivatives were obtained. Theoretical and experimental studies show that the hydroxylammonium salt (7) is highly dense, and has excellent detonation performance with acceptable thermal stablity and sensitivities, which are superior to those of RDX.
由于高硝化富氮杂环是高能量密度材料中的重要结构单元，针对此类新型分子的开发已开展了广泛研究。一种由三唑环、硝氨基和二硝甲基组成的高能基团——3-二硝甲基-5-硝氨基-1,2,4-三唑已被设计并合成出来。通过与富氮阳离子配对，获得了几种离子衍生物。理论和实验研究表明，羟铵盐（7）密度高，具有优异的爆轰性能，热稳定性和感度也在可接受范围内，优于黑索今。
