Energetic compounds based on a new fused Bis[1,2,4]Triazolo[1,5-b;5′,1′-f]-1,2,4,5-Tetrazine

Tailoring Transition Metals and Biuret into Laser-Ignitable Energetic Coordination Polymers with Improved Oxygen Balance and Multidentate Coordination Structures

“…In contrast, three-dimensional ECPs usually have a frame structure with holes and low density. The entire structure separates the ligands from each other, reducing the mechanical sensitivity in the presence of nitrate plasma and increasing oxygen balance and total energy. − …”

Regulating the Thermal Stability and Energy of Fused-Ring Energetic Materials by Hydrazo Bridging and Hydrogen-Bonding Networks

“…The discovery of new energetic materials (EMs) is one of the growing topics in the field of materials science. − One of the long-term objectives in this field is how to design and synthesize new energetic compounds with high energy, good safety, and high thermal stability. − Recent advances have shown that conjugated skeletons, strong intramolecular hydrogen bonds, and π–π interactions, which are structural features of traditional heat-resistant and insensitive EMs such as 1,3,5-triamino-2,4,6-trinitro-benzene (TATB) and 2,6-diamino-3,5-dinitro-pyrazine-1-oxide (LLM-105), contribute to the low sensitivity and high thermal stability of EMs. − Besides, NN/N–N bonds and nitro groups can increase the density and positive heat of formation (Δ H f ) and lead to the high energy density of EMs such as 1,3,5-trinitro-2,4,6-trinitroaminobenzene (TNTNB), 1,5-diaminotetrazole-4N-oxide (SYX-9), and 2,2′-azo-bis­(5-azidotetrazole) . The group of Prof. Ganapathy Vaitheeswaran made some constructive investigations by using calculation methods based on well-known EMs such as ammonium dinitramide (ADN), potassium dinitramide (KDN), 5-aminotetrazole (5-AT), 3,3′-dinitro-5,5′-bis-1,2,4-triazole-1,1′-diolate (DNBTO), 4,4′-bis­(nitramino)­azofurazan (DNAF), and octanitrocubane (ONC), which also support the above rules. − Bicyclic azolo azines constitute a family of nitrogen-rich conjugated 5/6-fused rings that allow all of the above structural features in one molecule, making them popular building blocks to construct new low-sensitivity and high-energy materials.…”

Iodine-containing furazan compounds: a promising approach to high-performance energetic biocidal agents

“…The traditional energetic materials consist of cycloaliphatic amine or aromatic hydrocarbon scaffolds and explosophoric groups like amino (-NH 2 ), nitro (-NO 2 ), azide (-N 3 ) and nitramine (-NHNO 2 ) groups. [16][17][18][19][20] Inspired by energetic materials, more and more polyiodo compounds with explosophoric groups or molecules have been designed in recent years. [21][22][23][24][25][26][27][28] Compared to polyiodo compounds without energy functional groups, these compounds have signicant advantages, including increased enthalpy of formation, improved oxygen balance, and increased gas production (Fig.…”
