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

Langmuir, Journal Year: 2021, Volume and Issue: 37(23), P. 7118 - 7126

Published: June 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.
