The design and construction of high-dimensional energetic metal organic frameworks (EMOFs) offer a promising approach to achieve a balance between stability and energetic performance. In this study, a 3D EMOF [Pb3(BTT)2]n was successfully explored and characterized. It exhibits high density, excellent stability, and solvent-free properties, as confirmed by single-crystal X-ray diffraction and laser initiation systems.
The design and construction of high-dimension energetic metal organic frameworks (EMOFs) are a promising approach to balance stability and energetic performance. Herein, 3D EMOF [Pb3(BTT)2]n (EMOF 1, H3BTT = 4,5bis(tetrazol-5-yl)-2H-1,2,3-triazole), which achieved integrating high density, excellent stability, and solvent-free, was successfully explored and accurately characterized. Single-crystal X-ray diffraction shows that it is orthorhombic and belongs to Pbca space group. The BTT3- ligand features a 11-dentate coordination (total 11 nitrogen atoms), which compacts the structure of EMOF 1, possesses high density (3.344 g cm-3), and exhibits outstanding thermal stability (Tp = 377.8 degrees C) and mechanical sensitivity (IS > 40 J, FS = 216 N). Its laser response process is tracked by laser initiation systems.
