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.
