摘要

用简单的方法合成了氨基-1,2,4-三唑和氨基-1,3,4-恶二唑取代1-羟基四唑衍生物。这些化合物具有较高的密度和生成热、广泛的氢键网络和π电子堆积等特点，表现出优异的爆轰性能和稳定性。值得注意的是，作为一种新的高能共晶，ato - n2h4与1,3,5,7-四硝基-1,3,5,7-四硝基杂环（HMX）相比，具有更优越的能量性能（Dv = 9306 m s−1,P = 31.3 GPa），并具有优异的热稳定性（Td = 329.0℃）。本研究为高能不敏感化合物的设计和制备提供了新的思路。

Constructing an energetic hydroxytetrazole with high thermal stability by linking aminotriazole to 1-hydroxytetrazole†

Amino-1,2,4-triazole- and amino-1,3,4-oxadiazole-substituted 1-hydroxytetrazole derivatives were synthesised via a simple method. These compounds exhibited excellent detonation performance and stability owing to their high density and heat of formation, extensive hydrogen bonding network, and π-electronic stacking. Notably, as a new energetic co-crystal, ATTO-N₂H₄ exhibited superior energy performance (D_v = 9306 m s⁻¹, P = 31.3 GPa) compared to 1,3,5,7-tetranitro-1,3,5,7-tetranitro-heterocycle (HMX) and exhibited excellent thermal stability (T_d = 329.0 °C). This study provides a new perspective on the design and preparation of insensitive high-energy compounds.
