In this work, bicyclic fused [1,2,4]triazolo[4,3-b]pyridazine was used to construct new low-sensitivity high-energy materials. Two exemplary compounds, 6,7-diamino-3,8-dinitro- [1,2,4]triazolo[4,3-b]pyridazine (1) and 7-amino-6-azido-3,8-dinitro-[1,2,4]triazolo[4,3-b]pyridazine (2), were synthesized and characterized. The properties of the energetic materials, including their detonation velocities (D_v: 8994 m·s⁻¹ for 1, 8819 m·s⁻¹ for 2) and detonation pressures (P: 34.1 GPa for 1, 32.4 GPa for 2) were evaluated based on their densities (ρ: 1.93 g·cm⁻³ for 1, 1.84 g·cm⁻³ for 2) and heats of formation (ΔH_f: 348 kJ·mol⁻¹ for 1, 684 kJ·mol⁻¹ for 2). Their impact and friction sensitivities were measured to be 20 J and > 360 N for 1 and 18 J and 360 N for 2. The onset decomposition temperatures of 1 and 2 were 234 °C and 217 °C, respectively; therefore, both compounds were highly energetic materials with low sensitivities and good thermostability.

在这项工作中，双环稠合[1,2,4]三唑并[4,3-b]哒嗪被用于构建新的低灵敏度高能材料。两种示例性化合物，6,7-二氨基-3,8-二硝基-[1,2,4]三唑并[4,3-b]哒嗪（1）和7-氨基-6-叠氮基-3,8-二硝基-合成并表征了[1,2,4]三唑并[4,3-b]哒嗪（2）。的高能材料，包括它们的爆速的属性（d _v：8994米·S ^-1为1，8819米·S ^-1为2）和爆轰压力（P：34.1 GPA为1，32.4 GPA为2）为根据其密度（ρ1.93克·平方厘米^-3为1，1.84克·平方厘米^-3为2），并生成热（Δ ħ _˚F：348千焦·摩尔^-1为1，684千焦·摩尔^-1为2）。测得它们的冲击和摩擦敏感度分别为20 J和1＞ 360 N和2 2分别为18 J和360N 。1和2的起始分解温度分别为234°C和217°C；因此，这两种化合物都是高能材料，灵敏度低且热稳定性好。
