摘　　要：以多氨基稠环化合物4,7⁃二氨基哒嗪并[4,5⁃c]氧化呋咱(4)为原料,分别与3⁃硝基⁃1,2,4⁃三唑⁃5⁃酮(NTO)及其它高氮类硝胺化合物构筑的富氮阴离子结合制备了一系列含能离子盐(5~11)。运用核磁共振、元素分析和红外光谱等分析方法对化合物(5~11)进行了结构表征,结合量子计算对3⁃硝基⁃1,2,4⁃三唑⁃5⁃酮的4,7⁃二氨基哒嗪并[4,5⁃c]氧化呋咱盐(6)进行^(15)N NMR谱分析,并通过X⁃射线单晶衍射技术对5,5′⁃二硝氨基⁃3,3′⁃偶氮⁃1,2,4⁃噁二唑的4,7⁃二氨基哒嗪并[4,5‑c]氧化呋咱盐(9)进行晶体结构解析。通过Explo5软件计算得到化合物的爆轰性能;采用BAM法测得化合物的撞击和摩擦感度。结果发现,5硝氨基四唑的4,7⁃二氨基哒嗪并[4,5⁃c]氧化呋咱盐(5)具有优异的爆轰性能和较低的感度,其爆速爆压分别为8816 m·s^(-1)和32.1 GPa,撞击感度和摩擦感度分别为15 J和200 N。A series of energetic salts(5-11)were synthesized by reacting polyamino⁃fused heterocyclic 4,7⁃diaminopyridazino[4,5⁃c]furoxan(4)with nitrogen⁃rich energetic acids including NTO or some other high⁃nitrogen nitroamino derivatives.The structures of 5-11 were characterized by nuclear magnetic resonance(NMR)spectroscopy,elemental analysis and infrared spectroscopy.In addition,the ^(15)N NMR spectrum of 6 was measured and assignedbased on the quantum calculations.The crys⁃tal structure of 9 was also confirmed by single crystal X⁃ray diffraction.The detonation properties of these compounds(5-11)were calculated by Explo5(version 6.05.02)software,and the impact and friction sensitivities were also measured.Among them,compound 5 exhibits good detonation performances(Dv:8816 m·s^(-1),P:32.1 GPa)and low sensitivities(IS:15 J,FS:200 N).
