Nitrogen-rich triazine, triazolo and tetrazolo-triazine-based energetic compounds: A new class of fluorinated organic explosives

This is the authors' abstract. We don't add key points for this paper.

s Various nitrogen-rich fluorinated energetic materials based on monocyclic triazine, fused triazolo-triazine, and tetrazolo-triazine backbones were synthesized and fully characterized using multinuclear magnetic resonance spectroscopy ( 1 H, 13 C, 19 F-NMR), infrared spectroscopy (IR), high-resolution mass spectrometry (HRMS) and elemental analysis (EA). Additionally, 4-azido-6-(trifluoromethyl)-1,3,5-triazin-2-amine (ATFT, 2 ) was confirmed using single-crystal X-ray analysis (SC-XRD). All the synthesized compounds possess good density (>1.75 g cm -3 ), moderate to good thermal decomposition temperature (149-196 °C), good detonation properties (VOD= 6754-8058 m s -1 ; DP=12.18-25.90 GPa), and excellent insensitivity (IS= 40 J, FS= 360 N). These findings provide new perspectives for the design of trifluoromethyl-containing energetic materials and also bring a new design of organic explosives with acceptable detonation properties.
