The construction and modification of novel energetic frameworks to achieve an ideal balance between high energy density good stability are a continuous pursuit for researchers. In this work, fused [5,6,5]-tricyclic framework was utilized as the host encapsulate oxidant molecules first time. A series new pyridazine-based [5,6] [5,6,5] polycyclic nitrogen-rich skeletons their derivatives were designed synthesized. Two strategies, amino oxidation host-guest inclusion, used modify skeleton in only one step. All compounds exhibit comprehensive properties (

A Dihydrazone as a Remarkably Nitrogen-Rich Thermostable and Insensitive Energetic Material

Organic Letters, Год журнала: 2023, Номер 25(32), С. 6082 - 6086

Опубликована: Авг. 9, 2023

Hydrogen bonds (H-bonds) in energetic compounds have a very pronounced effect on physicochemical properties such as density, thermal stability, sensitivity, and solubility. Now strategy to synthesize nitrogen-rich materials with overall good properties, which stem from the synergetic effects of inter- or intramolecular H-bonds, is reported. 1,2-Dihydrazono-1,2-di(1H-tetrazol-5-5-yl)ethane (4), new thermostable insensitive material, obtained reaction dioxime (2) hydrazine hydrate. The exchange oxime (NOH) hydrazone (NNH2) functionality results reduced acidic character low solubility water, make it remarkably suitable for practical use. While detonation velocity 4 comparable RDX, has an advantage high nitrogen content (76%) stability (275 °C) toward external stimuli.

Novel Heat-Resistant Energetic Compounds Based on the Pyrazole–Triazole Backbone with Functional Groups

Crystal Growth & Design, Год журнала: 2024, Номер 24(8), С. 3160 - 3169

Опубликована: Апрель 6, 2024

Developing heat-resistant explosives with excellent comprehensive performance is currently a significant challenge. Herein, series of new energetic compounds based on pyrazole and triazole were designed synthesized. Their structures characterized by nuclear magnetic resonance (NMR), Fourier transform infrared spectroscopy (FT-IR), elemental analysis (EA), mass spectrometry (MS), the four ion salts also confirmed single-crystal X-ray diffraction. In light crystal data, theoretical calculations including Hirshfeld surfaces, two-dimensional (2D) fingerprint, interaction region indicator used to explain relationship between their structure, stability, safety studying intermolecular hydrogen bonding stacking methods. thermal behavior detonation have been systematically studied. NBDAT its exhibit density ranging from 1.772 1.901 g cm–3 velocity pressure 8234 8812 m s–1 27.0 31.4 GPa, respectively. Among them, neutral has an 1.851 cm–3, decomposition temperature 354.5 °C, superior performances D = s–1, P 30.5 low sensitivity IS 40 J, FS 360 N, making it promising candidate replace 1,3,5-triamino-2,4,6-trinitrobenzene (TATB) hexanitrostilbene (HNS) as explosives.
