“…An efficient strategy for tailoring tetrazole‐based energetic materials is the formation of energetic salts, which have been proved to possess advantages over conventional nonionic molecules, such as lower vapor pressures and higher density, and more insensitive towards stimuli . After combine with the nitrogen‐rich cations or anions, the tetrazole‐based energetic salts have more N−N, N=N, and C−N bonds in molecule structures, leading to higher positive heat of enthalpy, which can finally guarantee the excellent detonation performances ,. Moreover, it is found to be an effective strategy to combine azoles into a complete molecule by a spacer atom or organo‐functional group.…”

A series of nitrogen‐rich energetic heterocyclic 1,1’‐dihydroxy‐5,5’‐azobistetrazole (AZO) salts are synthesized with ethylenediammonium (1), hydrazinium (2), semicarbazidium (3), guanidinium (4), 1‐amino‐1,2,3‐triazolium (5), 4‐amino‐1,2,4‐triazolium (6) and 5‐amino‐tetrazolium (7). The salts have characterized through elemental analysis, Fourier Transform infrared spectroscopy (FT‐IR) spectroscopy, 1H NMR, 13C NMR and mass spectrometry. The crystal structures determined by single crystal X‐ray diffraction. The thermal decomposition behaviors investigated by using the DSC and TG‐DTG technologies. The enthalpies of formation are calculated through the combustion heat data measured through the oxygen bomb calorimetry. All the salts have acceptable thermal stability with the highest decomposition temperature of 301.8 °C, excellent high positive formation enthalpies ranging from 350.5 kJ mol−1 to 1500.3 kJ mol−1, and good insensitivity to outer stimuli compared to the traditional RDX. The promising detonation parameters of the salts yield detonation velocities (D) and pressures (P) are ranging from 7327 m s−1 to 8931 m s−1, and from 21.7 GPa to 32.7 GPa. Considering the advantage, it is possible to prepare these nitrogen‐rich energetic salts as promising energetic materials. It's hoped that the present author's research contributed to the expansion and application of the chemistry of 1,1’‐dihydroxy‐5,5’‐azobistetrazole.
