Abstract
- The design, synthesis, physical properties, and calculated detonation performances of two skeleton isomeric energetic compounds containing tetrazole were introduced. By changing the chemical modification sites of the original fused-pyrimidine skeleton, a new pyrazolo[5,1-c][1,2,4]triazine framework was designed to compensate for the inability to functionalize CH sites in the original backbone. The potential energetic molecule 4-amino-8-nitro-3-(1H-tetrazol-5-yl)pyrazolo[5,1-c][1,2,4]triazin-7(6H)-one (PTT) was synthesized and characterized, which exhibits a moderate thermal decomposition temperature of 278.8 °C, good detonation velocity of 8620 m s<superscript>−1</superscript>, and desirable mechanical sensitivity. A comprehensive comparison between original 2-nitro-6-(1H-tetrazol-5-yl)-[1,2,4]triazolo[1,5-a]pyrimidin-7-amine (NPT) and PTT suggests that positional isomerism modulation holds broad prospects in the design of energetic materials.
