Series of AzTO-Based Energetic Materials: Effect of Different π–π Stacking Modes on Their Thermal Stability and Sensitivity

Langmuir, Год журнала: 2021, Номер 37(23), С. 7118 - 7126

Опубликована: Июнь 3, 2021

π-Stacking is common in materials, but different π–π stacking modes remarkably affect the properties and performances of materials. In particular, weak interactions, π-stacking hydrogen bonding, often have a great impact on stability sensitivity high-energetic compounds. Therefore, several energetic materials based 1,1′-dihydroxyazotetrazole (1) with nearly flat structure, such as salts aminoguanidine (2), 1,3-diaminoguanidine (3), imidazole (4), pyrazole (5) triaminoguanidine (6), cocrystal 2-methylimidazole (7), were designed synthesized. Based single-crystal diffraction data, thermal decomposition behaviors, mechanical test, compounds 4, 5, 7 face-to-face display outstanding insensitivity.

ACS Applied Materials & Interfaces, Год журнала: 2022, Номер 14(33), С. 37975 - 37981

Опубликована: Авг. 11, 2022

Thermal stability is one of the most significant properties for safety energetic materials, finding a stable skeleton with suitable groups always primary test. In this work, an unusual aminohydrazone cyclization strategy was used in synthesis new series gem-dinitro 1,2,4-triazolo[4,3-b][1,2,4,5]-tetrazine compounds desirable thermal (≥197 °C). All were fully characterized by infrared (IR), NMR, differential scanning calorimetry, single crystal X-ray diffraction, and elemental analysis. The decomposition temperature potassium salt 2 288 °C, reaching level HMX. these performances have demonstrated effective innovatively combining geminal dinitro fused rings.
