Zwitterionic Energetic Materials: Synthesis, Structural Diversity and Energetic Properties

Chemistry - An Asian Journal, Journal Year: 2024, Volume and Issue: 19(17)

Published: June 10, 2024

Abstract Zwitterionic compounds are an emergent class of energetic materials and have gained synthetic interest many in the recent years. Due to their better packing efficiencies strong inter/intramolecular electrostatic interactions, they often ensue superior properties than salt analogues. A systematic review from perspective design, synthesis, physicochemical evaluation zwitterionic is presented. Depending on parent ring(s) used for synthesis type moieties bearing positive negative charges, different classes materials, such as primary explosives, secondary heat resistant oxidizers, etc., may result. The some also compared with analogous salts. This will encourage readers explore possibility designing new materials.

From the standpoint of chemical structures, organic backbones energetic materials can be classified into aromatic rings, nonaromatic and open chains. Although category compounds exhibits several advantages in regulation properties, heterocycles, assembling nitramino explosophores with simple alkyl bridges, still have prevailed benchmark materials. The methylene bridge plays a pivotal role constructions classic heterocycle-based compounds, e.g., hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX), whereas ethylene is core moiety state-of-the-art explosive 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane (CL-20). In this context, it great interest to employ practical bridges assemble nitrogen-rich thereby expanding structural diversity materials, bridged fused poly-heterocycles. Furthermore, alkyl-bridged poly-heterocycles highlight potential for chain type review, development linking heterocycles presented, perspective newly constructed summarized future design advanced

Revamping the structure of energy storage is an efficient strategy for striking a balance between performance and sensitivity energetic materials to achieve high reduced sensitivity. In continuation prior research, this study utilized ligand 3,5-dimethyl-1H-pyrazole-4-carbonhydrazide (DMPZCA) innovatively designed synthesized compound ECCs [Cu(HDMPZCA)2(ClO4)2](ClO4)2·2H2O (ECCs-1·2H2O). Compared with former solvent-free ECCs-1 refers innovative material characterized by dual involving ionic salts coordination compounds. Due these unique structures, exhibits increased [ClO4-] content, higher oxygen constant (OB = -7.9%), improved mechanical (IS 8 J, FS 32 N). Theoretical calculations support superior detonation ECCs-1. Additionally, experimental results confirm its ignition capability through lower-threshold lasers highlight outstanding initiation potential explosive power, making it suitable candidate primary explosives.

Influence of nitroamino−nitroimino tautomerism: A useful theoretical supplement for nitroamino-based energetic materials

Energetic Materials Frontiers, Journal Year: 2023, Volume and Issue: 4(4), P. 229 - 234

Published: Nov. 14, 2023

Nitroamino is an ideal high-energy group for constructing energetic compounds. The skeletal isomerization of nitroamino to nitroimino forms intramolecular HBs, thus resulting in better density, thermal stability and sensitivity. However, it difficult find the same environment comparative analysis. A new compound, 5-Nitroamino-8-nitroimino-1,4-dihydropyrazino [2,3-d]pyridazine-2,3-dione (3), was designed synthesized. symmetric skeleton pyrazino [2,3-d]pyridazine provides both groups. By using a variety computational graphical methods, theoretical support nitroamino-based materials produced by thoroughly examining influence between nitroimino.
