采用多种N-官能化策略合成了一类3，6-二硝基吡唑并[4，3-c]吡唑类含能化合物。随后，通过酸碱反应合成了9种N，N-（3，6-二硝基吡唑并[4，3-c]吡唑-1，4-二基）二硝酰胺阴离子衍生物，并通过红外光谱、多核核磁共振谱和元素分析对其进行了表征。其中四个化合物的结构通过单晶X-射线衍射得到进一步证实。根据其不同的物理和爆轰性能，这些化合物显示出作为现代含能材料的良好潜力，并可分为绿色起爆药、高性能起爆药、富燃料推进剂和推进剂氧化剂。
A family of 3,6-dinitropyrazolo[4,3-c]pyrazole-based energetic compounds was synthesized by using versatile N-functionalization strategies. Subsequently, nine ionic derivatives of the N,N-(3,6-dinitropyrazolo[4,3-c]pyrazole-1,4-diyl)dinitramidate anion were prepared by acid-base reactions and fully characterized by infrared, multinuclear NMR spectra, and elemental analysis. The structures of four of these compounds were further confirmed by single-crystal X-ray diffraction. Based on their different physical and detonation properties, these compounds exhibit promising potential as modern energetic materials and can be variously classified as green primary explosives, high-performance secondary explosives, fuel-rich propellants, and propellant oxidizers.
