Abstract

A novel Ag(I) energetic MOF [Ag16(BTFOF)9]n·[2(NH4)]n () assembled with Ag(iI ions and a furazan derivative, 4,4'-oxybis[3,3'-(1H-5-tetrazol)]furazan (H2BTFOF) was successfully synthesized and structurally characterized, featuring a three-dimensional porous structure incorporating ammonium cations. The thermal stability and energetic properties were determined, revealing that the 3D energetic MOF had an outstanding insensitivity (IS > 40 J), an ultrahigh detonation pressure (P) of 65.29 GPa and a detonation velocity (D) of 11.81 km cm(-3). In addition, the self-accelerating decomposition temperature (TSADT) and the critical temperature of thermal explosion (Tb) are also discussed in detail. The finding exemplifies that the assembly strategy plays a decisive role in the density and energetic properties of MOF-based energetic materials.

摘要

一种由银（I）离子与呋喃唑衍生物4,4'-氧双[3,3'-(1H-5-四唑)]呋喃（H2BTFOF）组装而成的新型含能金属有机框架[Ag16(BTFOF)9]n·[2(NH4)]n（）已成功合成并进行了结构表征，其具有包含铵阳离子的三维多孔结构。测定了其热稳定性和含能性能，结果表明该三维含能金属有机框架具有出色的钝感度（IS>40 J）、65.29 GPa的超高爆轰压力（P）和11.81 km cm(-3)的爆轰速度（D）。此外，还详细讨论了自加速分解温度（TSADT）和热爆炸临界温度（Tb）。该发现表明组装策略在基于金属有机框架的含能材料的密度和含能性能中起着决定性作用。
