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). Theoretical analysis that effect “NH2-NO2-NH2” intramolecular hydrogen bonding interaction may be main reason for causing heat-resistance imidazolopyridazine materials. results suggest promising building block candidate
