The fully nitrated azole-based energetic materials are high in energy but unstable, which limits their practical applications. Tetrazole, with its formation enthalpy and intrinsic acidic hydrogen, can react nitrogen-rich bases, further enhancing both the stability. Consequently, we replaced C-nitro group 1,2,4-triazole C-tetrazole, resulting synthesis of 1-(trinitromethyl)-5-nitroimino-3-tetrazole-1,2,4-triazole (TNTT, 4). salts 1-(dinitromethyl)-5-nitroimino-3-tetrazole-1,2,4-triazole (DNTT) were synthesized via a metathesis reaction bases derived from silver salts. All newly prepared structures (4 7–10) characterized by using single-crystal X-ray diffraction. Among these compounds, salt 9 exhibited best overall performance, an elevated decomposition temperature (Td = 181 °C), mechanical stability (IS 17.5 J, FS 216 N) detonation velocity (D 9337 m s–1) surpassed those HMX, making it promising candidate for secondary explosives. Additionally, N2H5+ 8 K+ 10 demonstrated low sensitivity ≥ 27.5 > 360 due to hydrogen-bonded organic frameworks metal–organic frameworks.

The design of high-energy-density materials (HEDMs) and the investigation energy limits have consistently represented a focal point significant challenge in research. This study prepared hydrogen-free compound, BLG-102, with high nitrogen content (66.6%) using an energetic block based on long chain (N6). BLG-102 has crystal density 1.85 g·cm-3, measured 1.82 g·cm-3. It also achieves zero oxygen balance (based CO), excellent enthalpy formation, good conjugate planarity aromaticity. demonstrates exceptional detonation performance velocity (VD = 9311 m·s-1) pressure (P 38.5 GPa). These values are superior to well-known compound RDX 8991 m·s-1, P 35.2 GPa), comparable HMX 9144 39.2 Nevertheless, exhibits slightly higher but acceptable sensitivity (IS 5 J, FS 54 N). remarkable capabilities laser initiation. Notably, 10 mg charge can effectively detonate 20 RDX, producing pore diameter 11.44 mm lead plate (2 thick). integrated approach concept─combining nitro, azide, structures 1,2,4-triazole framework─significantly enhances compounds. breaks through limit already known 1,2,4-triazole-based compounds provides new idea for synthesis HEDMs performance.

The field of high energy density materials faces a long-standing challenge to achieve an optimum balance between and stability. While energetic salt formation via combination oxygen- nitrogen-rich anions (providing energy) with nitrogen-containing cations stability) has been proven approach for improving physical stability, constraints such as lowering performance remain unresolved. This can be addressed by utilizing oxygen-containing formation. However, this is rarely explored because its synthesis challenging. In work, we have designed oxygen-rich cationic precursor
