Treatment of 1-amino-1,2,3-triazole with sodium dichloroisocyanurate led to isolation of 1,1'-azobis-1,2,3-triazole, which was well characterized. Its structure was determined by X-ray crystallographic analysis, and its thermal stability and photochromic properties were investigated.
A new family of high-nitrogen compounds, that is, polyazido- and polyamino-substituted N,N'-azo-1,2,4-triazoles, were synthesized in a safe and convenient manner and fully characterized. The structures of 3,3',5,5'-tetra(azido)-4,4'-azo-1,2,4-triazole (15) and 3,3',5,5'-tetra(amino)-4,4'-azo-1,2,4-triazole (23) were also confirmed by X-ray diffraction.(More)
In recent years, research in the field of carbon nanomaterials (CNMs), such as fullerenes, expanded graphite (EG), carbon nanotubes (CNTs), graphene, and graphene oxide (GO), has been widely used in energy storage, electronics, catalysts, and biomaterials, as well as medical applications. Regarding energy storage, one of the most important research(More)
A family of 4,4',6,6'-tetra(azido)azo-1,3,5-triazine-N-oxides was designed and investigated by theoretical method. The effects of the N→O bond on the properties of TAAT-N-oxides, such as density, heat of formation, and detonation performance, were discussed. By comparison with the bond-dissociation energy of the weakest bond and the electrostatic(More)
Cyanoguanidines as well as azoles are important bioactive groups, which play an important role in the medical application; meanwhile, the high nitrogen content makes them excellent backbones for energetic materials. A Novel and simple method that combined these two fragments into one molecular compound was developed through the transformation of dicyanamide(More)
A series of trinitromethyl/trinitroethyl substituted derivatives of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazatetracyclo[5,5,0, 0(3.11),0(5.9)] dodecane (CL-20) were designed and investigated by theoretical methods. Intramolecular interactions between the trinitromethyl/trinitroethyl and the cage were investigated. The effects of(More)
A family of energetic salts with high thermal stability and low impact sensitivity based on an oxygen-containing cation, 2,4-diamino-1,3,5-triazine-6-one, were synthesized and fully characterized by IR and multinuclear ((1)H, (13)C) NMR spectroscopy, elemental analysis, and differential scanning calorimetry. Insights into their sensitivities towards impact,(More)
