合成了一种新的含能MOF [Cu 2（to）（dns）（H2O）]n（1; H2 to = 1，2，4-三唑-5-酮，H2 dns = 3，5-二硝基水杨酸），并对其结构进行了表征.单晶X-射线衍射分析表明1具有紧凑的3D结构。值得注意的是，一个硝基的两个氧原子以异步反模式与两个Cu离子配位，这降低了其灵敏度，但对其爆炸性能没有影响。热重和差示扫描量热分析结果表明，MOF 1具有快速的热分解过程和上级热稳定性。用Kissinger和Ozawa方法研究了1的非等温放热动力学。感度试验和爆轰性能计算表明，1具有作为绿色炸药的潜力。
A new energetic MOF, [Cu2(to)(dns)(H2O)]n(1; H2to = 1,2,4‐triazol‐5‐one, H2dns = 3,5‐dinitrosalicylic acid), has been synthesized and structurally characterized. Single‐crystal X‐ray diffraction analysis revealed that1possesses a compact 3D architecture. Noteworthy, the two oxygen atoms of one nitro coordinate to two CuIIions in asyn‐antimode, which decreases its sensitivity but has no influence on its explosive properties. Based on the results of thermogravimetric and differential scanning calorimetry analyses, MOF1displays a rapid thermal decomposition process and superior thermostability. The non‐isothermal kinetics of the exothermic process of1were studied by the methods of Kissinger and Ozawa. The sensitivity tests and calculated detonation properties show that1has the potential to be used in green explosives.
