Fused Azo-Bridged Triazolo-Pyridazine-Derived Energetic Materials
In this study, we synthesized a series of novel fused-ring azo-bridged compounds incorporating nitramine, azide, and hydrazine functional groups. The newly synthesized compounds exhibited promising energetic properties, including good densities (1.71-1.76 g cm<sup>-3</sup>), good detonation velocities (7203-8104 m s<sup>-1</sup>), controlled impact (2.5-40 J), and friction sensitivities (120-360 N), and the thermal stability ranged from 128 °C to 300 °C. Notably, compound <b>4</b> demonstrated exceptional thermal stability (300 °C) as an heat-resistant explosive, while compound <b>7</b> emerged as a highly promising lead-free primary explosive with an ultralow minimum primer charge of just 40 mg.
