4-nitro-5-(1,2,4-triazol-3-yl)-2H-1,2,3-triazole compounds in combination with different energetic moieties like amino, nitrimino, nitro, and azo groups is presented. Furthermore, a novel family of energetic salts based on the 4-nitro-5-(5-R-1,2,4-triazol-3-yl)-2H-1,2,3-triazole (2: R = nitrimino; 3: R = nitro) monoanion and dianion were controllably synthesized. All new compounds were fully characterized
四个中性的4-硝基-5-(1,2,4-三唑-3-基)-2 H -1,2,3-三唑化合物与不同的高能基团(如氨基,亚硝基,硝基和三氟甲基)结合合成给出了偶氮基团。此外,基于4-硝基-5-(5-R-1,2,4-三唑-3-基)-2 H -1,2,3-三唑的新型高能盐家族(2:R =可控制地合成了亚硝基亚胺;3:R =硝基)一价阴离子和二价阴离子。所有新化合物均通过IR和多核NMR光谱,元素分析和DSC测量得到了充分表征。的分子结构2,3,8和17通过单晶X射线衍射确定。此外,分别使用Gaussian 09和EXPLO5 v6.01程序计算了所有高能化合物的形成热和爆轰性能。实验和理论评估都显示了这些高能化合物的良好性能,例如高密度,正形成热,高热稳定性,良好的敏感性和出色的爆炸性能。其中,6,7,14至16,24和25表现出有利的整体性能的高能材料。
