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.

Abstract Azo compounds with a high density, enthalpy, and excellent detonation performance have received increasing research attention. The conventional method of chemical dehydrogenation that is used to form azo involves the use strong oxidants, resulting in environmental pollution. Electrochemical organic synthesis considered an old new technology. In this work, azofurazan tetrazole {H2AzFT; 5,5′-[diazene-1,2-diylbis(1,2,5-oxadiazole-4,3-diyl)]bis-1H-tetrazole} hydroxytetrazole (H2AzFTO) were synthesized by green efficient electrochemical coupling 5-(4-aminofurazan-3-yl)-1H-tetrazole 5-(4-aminofurazan-3-yl)-1-hydroxytetrazole, respectively. structures H2AzFT (NH4)2AzFTO fully characterized infrared spectroscopy, nuclear magnetic resonance, elemental analysis, their thermal stabilities determined differential analysis.

The stability and detonation properties of energetic coordination polymers (ECPs) are usually directly related to the selection ligands. However, different metals ligands may form structures, which will greatly affect performance ECPs. Three-dimensional (3D) metal–organic frameworks (EMOFs) exhibit enhanced performances modest compared with one-dimensional (1D) two-dimensional (2D) In this work, an internal salt H2TzTO (5-(1H-1,2,4-triazol-4-ium-3-yl)-1H-tetrazol-1-olate) high was selected as ligand coordinated four metal centers, Na(I), K(I), Co(II), Ni(II), three ECPs, named [Na(HTzTO)(H2O)]n·0.5H2O, Co(HTzTO)2(H2O)2, Ni(HTzTO)2(H2O)2·2H2O, one EMOF [K(HTzTO)]n, respectively. compounds showed excellent thermal [decomposition temperature (Td) ≥ 263 °C] [detonation velocity (D) 8587 m·s–1 pressure (P) 33.8 GPa], but their due influence center structure. Among them, [K(HTzTO)]n Co(HTzTO)2(H2O)2 surprising (Td = 344 347 °C, respectively) formation face-to-face π–π stacking in enhances molecules.
