以含能阴离子为配体的含能金属有机骨架（MOFs）可用作新一代炸药。许多强阴离子被引入到含能MOFs中以改善其性能，然而羟基作为含能MOFs的常见基团却很少被研究。在这篇文章中，我们提出了两个例子的能量MOFs（[Cu（atz）（NO3）（OH）]n）和[Zn（ata）（OH）]（atz = 4-氨基-1，2，4-三唑; ata = 5-氨基-1H-四唑）与羟基作为配体。晶体结构分析表明，这两个化合物具有紧凑的二维（2-D）结构，密度分别高达2.41克厘米3和2.54克厘米，分别。这两种化合物具有优良的物理化学性质。结果表明，羟基作为配体可以很好地提高含能MOFs的密度，从而提高其爆轰性能。预计这项工作将为含能MOFs的发展开辟新的方向。
Energetic metal organic frameworks (MOFs) with energetic anions as ligands can be used as new-generation explosives. Many powerful anions have been introduced into energetic MOFs to improve the properties; however, the hydroxyl as a common group for energetic MOFs has rarely been studied. In this article, we present two examples of energetic MOFs ([Cu(atz)(NO3)(OH)]n) and [Zn(ata)(OH)] (atz = 4-amino-1,2,4-triazole; ata = 5-amino-1H-tetrazole) with the hydroxyl group as the ligand. Crystal structure analyses reveal that the two compounds possess compact two-dimensional (2-D) structures with densities up to 2.41 g cm 3 and 2.54 g cm , respectively. These two compounds have excellent physicochemical properties. The results demonstrate that a hydroxyl group as the ligands could commendably increase the densities of energetic MOFs, thereby enhancing the detonation performance. It is anticipated this work will open a new direction for the development of energetic MOFs.
