Energetic metal–organic frameworks (EMOFs) with a high oxygen content are currently hot spot in the field of energetic materials research. In this article, two series EMOFs different ligands were obtained by reacting 1-(trinitromethyl)-1H-1,2,4-triazole-3-carboxylic acid (tntrza) metal iodide and nitrate, respectively. Furthermore, their structure, thermal stability, decomposition kinetics, energy performance fully characterized. The research results revealed that synthesized possess wide range density (ρ = 1.88∼2.595 g cm–3), balance (OB(CO2) −21.1∼ −4.3%), acceptable (D 7.73∼8.74 km s–1 P 28.1∼41.1 GPa). difference OB(CO2) caused ligand structure properties has great impact on distribution gas-phase products after these EMOFs. Noteworthy, [Ag(tntrza)]n is particularly prominent among EMOFs, not only because its excellent detonation 8.74 41.1 GPa) endowed extremely 2.595 cm–3) −4.3%) but also effective catalytic effect ammonium perchlorate (AP). This article broadens horizon for study oxygen-enriched effects helps understand mechanism nitroform dinitro groups.

In recent years, molecular perovskite energetic materials have attracted more attention because of their simple synthesis processes, high thermal stabilities, excellent performances, and great significance as a design platform for materials. To explore the possibility application in heat-resistant explosives, four silver(I)-based compounds, (H2A)[Ag(ClO4)3], where H2A = piperazine-1,4-diium (H2pz2+) PAP-5, 1-methyl-piperazine-1,4-diium (H2mpz2+) PAP-M5, homopiperazine-1,4-diium (H2hpz2+) PAP-H5, 1,4-diazabicyclo[2.2.2]octane-1,4-diium (H2dabco2+) DAP-5, were synthesized by one-pot self-assembly strategy structurally characterized. The single-crystal structures indicated that DAP-5 possess cubic while PAP-H5 possesses hexagonal structure. Differential analyses showed onset decomposition temperatures are >308.3 °C. For PAP-5 they not only exceptional calculated detonation parameters (D values 8.961 8.534 km s-1 P 42.4 37.9 GPa, respectively) but also proper mechanical sensitivity (impact sensitivities ≤10 J 3 friction ≤5N both DAP-5) thus interest potential primary explosive components.

It is highly desired but still remains challenging to design a primary explosive-based nanoparticle-encapsulated conductive skeleton for the development of powerful yet safe energetic films employed in miniaturized explosive systems. Herein, proof-of-concept electrochemical preparation metal-organic frameworks (MOFs) derived porous carbon embedding copper-based azide (Cu(N3 )2 or CuN3 , CA) nanoparticles on copper substrate described. A Cu-based MOF, i.e., Cu-BTC fabricated based anodized Cu(OH)2 nanorods, as template, achieve CA/C film through pyrolysis and azidation. Such film, which woven by numerous ultrafine nanofibers, favorably demonstrates excellent energy release (945-2090 J g-1 ), tunable electrostatic sensitivity (0.22-1.39 mJ), considerable initiation ability. The performance superior most reported explosives, since CA contribute high brisance protection network. Notably, growth mechanism further disclosed detailed experimental investigation density functional theory (DFT) calculation. This work will offer new insight develop CA-based applications advanced
