This research demonstrates improved energy performance and stability in polynitro tetrazoles using fluorodinitromethyl, indicating gains in energetic materials.
Fluorodinitromethyl is a crucial substituent for energetic materials (EMs), known for its superior thermal stability compared to other polynitro groups. In this study, we incorporated the fluorodinitromethyl group into a tetrazole backbone to achieve a balance between stability and energetic performance. The compound 2‐(dinitromethyl)‐5‐(fluorodinitromethyl)‐2 H ‐tetrazole and its corresponding energetic salts were designed, synthesized through optimized routes, and thoroughly characterized. These compounds demonstrate high densities, positive enthalpy of formation, and excellent detonation properties. Compared to its trinitromethyl analog, this fluorodinitromethyl tetrazole exhibits significantly enhanced stability, density, and performance.
