High-Density Energetic Materials with Low Mechanical Sensitivity and Twinning Derived from Nitroimidazole Fused Ring.

ABSTRACT: The innovative synthesis of 3,8-dibromo-2,9-dinitro-5,6-dihydrodiimidazo [1,2-a:2',1'-c]pyrazine and 3,9-dibromo-2,10-dinitro-6,7-dihydro-5H-diimidazo [1,2-a:2',1'-c][1,4]diazepine is described in this study. The tricyclic fused molecular structures are formed by the respective amalgamation of piperazine and homopiperazine with the imidazole ring containing nitro. Compound 1 and 2 possess excellent high-density physical properties (ρ₁ = 2.49 g/cm³, ρ₂ = 2.35 g/cm³) due to the presence of a fused ring structure and Br atom. In addition to their high density, they have high decomposition temperatures (T_d > 290 °C) which means that they have excellent thermal stability and can be used as potential heat-resistant explo
