key directions of energetic materials research. In this study, a novel monocyclic hydroxytetrazole derivative (3) with high stability was prepared, and a series of insensitive energetic ionic salts were derived from it. Benefiting from their outstanding performance in terms of density, 3D hydrogen bonding and π-electron interactions, these salts are excellent in both detonation performance (D = 8709
兼具高稳定性和优异能量性能的高效炸药是含能材料研究的重点方向之一。本研究制备了一种具有高稳定性的新型单环羟基

生物( 3 ),并由此衍生出一系列不敏感的高能离子盐。得益于它们在密度、3D 氢键和 π 电子相互作用方面的出色表现,这些盐在爆轰性能(D = 8709 至 9314 ms -1和P = 29.9 至 35.6 GPa)和热稳定性(T d = 193.0–232.2 °C)。
肼盐 ( 2 ) 具有高爆轰性能 ( D= 9314 ms -1和P = 35.6 GPa),由于其高密度 ( ρ = 1.71 g cm -3 ) 和高形成热 (Δ f H = 563.2 kJ mol -1 = 3.19 kJ g -1 )。此外,2 的高热稳定性(T d = 232.0 °C)和低机械灵敏度(IS = 30 J 和 FS = 360 N)也是HMX 和 TKX-50 无法比拟的。这些改
