In recent years, driven by ever-increasing application of energetic materials in deep-seated mineral resource exploitation and aerospace engineering, the mining of advanced safe energetic materials with significant thermal stability has drawn widespread publicity. Here, a tricyclic bridged energetic compound 2-amino-4,6-bis(3,5-diamino-4-nitropyrazol-1-yl)-1,3,5-triazine () was prepared using simple synthetic route. Furthermore, an interesting highly thermostable nitrogen-rich perchlorate, , was prepared by the self-assembly reaction of and HClO, displaying a thermal decomposition peak temperature of 375.9 °C. Moreover, exhibits good detonation velocity ( = 8187 m s) and insensitivity (IS = 50 J, FS > 360 N), thereby being promising candidates for advanced insensitive high-energy materials.
近年来，在含能材料在深部矿产资源开采和航空航天工程中应用日益增加的推动下，具有显著热稳定性的先进安全含能材料的研制受到广泛关注。在此，采用简单的合成路线制备了一种三环桥连含能化合物2-氨基-4,6-双(3,5-二氨基-4-硝基吡唑-1-基)-1,3,5-三嗪()。此外，通过与高氯酸的自组装反应制备了一种有趣的高热稳定性富氮高氯酸盐，其热分解峰值温度为375.9℃。此外，表现出良好的爆速(=8187 m s)和钝感度(IS = 50 J，FS>360 N)，因此有望成为先进钝感高能材料的候选物。
