Through an in‐situ controllable synthetic strategy, an energetic metal–organic framework comprising a gem‐dinitromethyl‐substituted dipotassium 4,5‐bis(dinitromethyl)‐1,2,3‐triazole with a “cage‐like” crystal packing was obtained. During its synthesis, trifluoroacetic acid played a significant role as an effective catalyst in the in‐situ generation of the gem‐dinitromethyl group. This new metal–organic framework displays a high density and high detonation velocity. Meanwhile, its detonation products are mainly nitrogen, suggesting it is also a “green” energetic material. The proposed strategy of incorporating gem‐dinitromethyl groups into a 1,2,3‐triazole (N₃) framework holds great promise for developing new‐generation lead‐free primary explosives with a high‐performing detonation level.

封面特色：基于可现场合成的1,2,3-三唑的宝石-二硝基甲基取代的高能金属-有机骨架（Chem。Asian J. 19/2018）

通过原位可控的合成策略，获得了一种高能金属-有机骨架，该骨架包括由宝石-二硝基甲基-取代的4,5-双（二硝基甲基）-1,2,3-三唑双钾和“笼状”晶体堆积。在其合成过程中，三氟乙酸在原位生成宝石二硝基甲基基团中起着有效催化剂的作用。这种新的金属有机框架显示出高密度和高爆轰速度。同时，它的爆炸产物主要是氮气，表明它也是一种“绿色”高能材料。将宝石-二硝基甲基基团合并到1,2,3-三唑（N ₃）框架对于开发具有高爆轰水平的新一代无铅初级炸药具有广阔的前景。有关更多信息，请参见杨洪伟，范桂娟等人的来文。就在第19期，2018页2786（：10.1002 / asia.201800722 DOI）。
