Nitrogen‐rich Compounds with Multiple Azole Rings: Gas Generant, Enthalpy Enhancer and Applicable Cationic Component

Abstract

Nitrogen‐rich polyazole derivatives were designed and synthesized from the commercially available 4,5‐dicyano‐2‐aminoimidazole. The relatively simple synthesis of multiple azole rings in desired compounds with good yields allows for an efficient scale‐up. All synthesized compounds were characterized by NMR and vibrational spectroscopy, elemental analysis, and DSC studies. The impact and friction sensitivities were measured by the BAM apparatus. The energy content of the target compounds was predicted by using density functional methods. Performing cautious characterization point out that these compounds offer a good combination of high nitrogen‐ and energy‐content with insensitivity towards friction and impact stimuli. These results indicate the superior potential of these nitrogen‐rich polyazole derivatives for enthalpy enhancement, gas generant, and cationic components in energetic salts.
