Skeleton modification is an effective way of tuning and achieving desired properties for energetic compounds. In this work, a series of energetic compounds based on the [1,2,4]triazolo[3,4- f ][1,2,4]triazine-8(7 H )-one backbone have been designed and synthesized. After the skeleton modification of compound 5 , the resulting compound 6 , which has the same type of energetic group, exhibits higher density (1.951 g cm −3 ), and better thermal stability and mechanical sensitivities than those of compound 5 . Moreover, its energetic hydrazinium salt 8 has a high detonation property ( D = 9003 m s −1 ; P = 30.9 GPa). This research may provide new insights into the design and synthesis of novel energetic compounds with balanced comprehensive properties. Skeleton modification can expand pathways to tune the comprehensive properties for energetic compounds. In this work, skeleton modification was applied to the preparation of a family of new nitramine substituted [1,2,4]triazolo[3,4- f ][1,2,4]triazine fused ring compounds.
