Cover Feature: Gem ‐dinitromethyl‐substituted Energetic Metal–Organic Framework based on 1,2,3‐Triazole from in situ Controllable Synthesis (Chem. Asian J. 19/2018)

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 (N 3 ) framework holds great promise for developing new‐generation lead‐free primary explosives with a high‐performing detonation level.
