Fused Triazolotriazine Bearing A Gem-Dinitro Group: A Promising High Energy Density Material

Six energetic compounds bearing the dinitromethyl group and based on the triazolotriazine fused ring skeleton were achieved. All structures were confirmed using infrared spectroscopy (IR), H-1 NMR and C-13 NMR spectroscopy, high-resolution mass spectrometry (HRMS) and differential scanning calorimetry (DSC). Among them, potassium salt and neutral compound 3,7-bis(fluorodinitromethyl)-[1,2,4]triazolo[5,1-c][1,2,4]triazin-4-amine exhibit high densities (2.06 g cm(-3) and 1.95 g cm(-3), respectively), detonation velocities of up to 9028 m s(-1), and excellent friction sensitivity (>360 N).
