Conjugated energetic salts based on 3,3′-((1E,1′E)-(2,4,6-trinitro-1,3-phenylene)bis(ethene-2,1-diyl))bis(2,4,6-trinitrophenol)

Abstract

Based on a design strategy that has resulted in conjugated energetic materials, 3,3′-((1E,1′E)-(2,4,6-trinitro-1,3-phenylene)bis(ethane-2,1-diyl))bis(2,4,6-trinitrophenol) and its nitrogen-rich salts were obtained and characterized via spectral and elemental analyses. These new molecules exhibit good thermal stability (T_d = 268.4–311.3 °C), especially for hydrazinium salt 4c, which is comparable to that of the benchmark HNS. Also, they exhibit low impact sensitivity (>40 J), high density (1.67–1.88 g cm⁻³), acceptable detonation properties (7268–8527 m s⁻¹, 26.7–34.1 GPa) and brisance parameters (103.9–144.4). The energetic properties of the salts suggest potential applications to new energetic materials.
