Polynitrogen energetic materials have become an important branch of high-energy-density materials. In this work, a theoretical exploration structures and thermal stability in polynitrogen compounds N6, N8, N10 was conducted based on synthesized azide pentazolate compounds. By employing wave function analyses kinetic simulations, the equilibrium geometries, properties bonds, indices to represent aromaticity were explored represented. addition, their crystal predicted, decomposition processes products ab initio molecular dynamics (AIMD) simulations transition-state calculations carried out. Moreover, barrier can be significantly increased by forming complexes with HMX CL-20. Compounds HMX–1, HMX–4, CL-20–1, CL-20–4 showed satisfactory compared salts.

A primary explosive is an ideal chemical substance for performing ignition in military and commercial applications. For over 150 years, nearly all of the developed explosives have suffered from various issues, such as troublesome syntheses, high toxicity, poor stability or/and weak performance. Now we report interesting example a with double perovskite framework, {(C6H14N2)2[Na(NH4)(IO4)6]}n (DPPE-1), which was synthesized using simple green one-pot method aqueous solution at room temperature. DPPE-1 free heavy metals, toxic organic components, doesn't involve any precursors. It exhibits good towards air, moisture, sunlight, heat has acceptable mechanical sensitivities. affords performance on par most powerful reported to date. promises meet challenges existing current explosives, this work could trigger more extensive applications perovskite.

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.

Exploration of advanced lead-free primary explosives is a challenging issue in the field energetic materials. Herein, we designed and synthesized novel N-rich copper bromate coordination compound (ECC) [Cu(ATRZ)(BrO3)2]n (BLG-1, ATRZ: 4,4'-azo-1,2,4-triazole) by simple one-step reaction. BLG-1 first reported three-dimensional (3D) ECC. Its interesting 3D reticular architecture contributed to its highest thermal decomposition temperature (Td: 226 °C) crystal density (ρ: 2.69 g cm-3) among ECCs. More importantly, charge as little 3 mg could reliably detonate compressed RDX, 1 CL-20. These incredible values indicated that had an ultra-powerful initiating ability far superior previously explosives. improved mechanical sensitivities (IS: 13 J; FS: N) electrostatic sensitivity (EDS: 240 mJ) compared with those typical lead-based explosive, lead azide 4J; 0.75N; EDS: 5 mJ).
