Synthesizing energetic metal–organic frameworks at ambient temperature and pressure has been always a challenge in the research area of energetic materials. In this work, through in situ controllable synthesis, energetic metal–organic framework gem‐dinitromethyl‐substituted dipotassium 4,5‐bis(dinitromethyl)‐1,2,3‐triazole with a “cage‐like” crystal packing was obtained and characterized. Most importantly, for the first time, we found that it could be successfully afforded with a catalytic effect of trifluoroacetic acid. This new compound exhibited its high density (2.04 g cm⁻³) at ambient temperature, superior detonation velocity (8715 m s⁻¹) to that of lead azide (5877 m s⁻¹) and comparable to that of RDX (8748 m s⁻¹). Its detonation products are mainly N₂ (48.1 %), suggesting it is also a green energetic material. The above‐mentioned performance indicates its potential applications in detonator devices as lead‐free primary explosive.

基于1,2,3-三唑的原位可控制合成过程中的宝石-二硝基甲基-取代的含能金属-有机骨架

在环境温度和压力下合成高能金属-有机骨架一直是高能材料研究领域的挑战。在这项工作中，通过原位可控制的合成，获得了具有“笼状”晶体堆积的高能金属-有机骨架宝石-二硝基甲基-取代的双钾4,5-双（二硝基甲基）-1,2,3-三唑。最重要的是，我们首次发现，三氟乙酸具有催化作用可以成功地获得它。这种新化合物在环境温度下表现出高密度（2.04 g cm ^-3），比叠氮化铅（5877 m s ^-1）的爆轰速度（8715 m s ^-1）更好，与RDX（8748 m s ^-1）相当）。其爆炸产物主要为N ₂（48.1％），表明它也是一种绿色高能材料。上述性能表明其在雷管设备中作为无铅初级炸药的潜在应用。
