摘　　要：发展具有高能、低感、高热稳定性的新型含能材料是人们一直追求的目标。本研究设计、合成了一系列基于四唑连4,8?双呋咱并[3,4?b,e]吡嗪(DFP)的含能离子盐。含能离子盐具有优异的综合性能,如热分解温度较高(Td:>260℃),感度较低(IS≥20 J,FS≥360 N)和爆速较高等(D>8800 m·s^(-1))。值得特别指出的是,化合物4e的热分解温度高达314℃,并且其爆速及撞击感度分别为9005 m·s^(-1)和25 J,是一种极具潜力的钝感高能量密度材料。The development of new energetic materials with high energy,low sensitivity,and high thermal stability is always desirable.In this study,a series of tetrazole-linked 4,8-dihydrodifurazano[3,4-b,e]pyrazine(DFP)based energetic salts have been synthesized and fully characterized.The as-synthesized energetic salts exhibited excellent comprehensive performances in terms of high decomposition temperature(Td>260℃),low mechanical sensitivity(IS≥20 J and FS≥360 N),and high detonation velocity(D>8800 m·s^-1).Notably,the thermal decomposition temperature of di(aminoguanidinium)-4,8-d(i 1H-tetrazol-5-yl)-difurazano[3,4-b,e]pyrazine(compound 4e)is up to 314℃,while its detonation velocity and impact sensitivity are highly desirable with the values of 9005 m·s^-1 and 25 J,respectively.Overall,these novel energetic compounds have shown their great-potential as insensitive high-energy-density materials.
