The construction of heat-resistant fused heterocyclic compounds are increasingly fascinating in the field energetic materials not only because it usually behaves high density but also shows excellent energy, thermal stability and low sensitivity. In present study, a novel imidazo[1,2-b]pyridazine ring-based explosive, 3,7-dinitroimidazo[1,2-b]pyridazine-6,8-diamine (4) was synthesized by three-step facile method. Compound 4 has (1.856 g•cm-3) sensitivity (IS =40 J, FS = 350 N). Meanwhile, good decomposition temperature 324°C, which is superior to conventional heat resistant explosive HNS (Td 318°C). addition, detonation performance compound (D=8336 m•s-1, P=27.25 GPa) significantly better than both TNT (D=6881 P=19.5 (D=7612 P=24.3GPa).

Abstract Zwitterionic compounds are an emergent class of energetic materials and have gained synthetic interest many in the recent years. Due to their better packing efficiencies strong inter/intramolecular electrostatic interactions, they often ensue superior properties than salt analogues. A systematic review from perspective design, synthesis, physicochemical evaluation zwitterionic is presented. Depending on parent ring(s) used for synthesis type moieties bearing positive negative charges, different classes materials, such as primary explosives, secondary heat resistant oxidizers, etc., may result. The some also compared with analogous salts. This will encourage readers explore possibility designing new materials.
