Azide-Based High-Energy Metal-Organic Framework with Enhanced Thermal Stability


We report the synthesis of Zn(C6H4N5)N3, a new three-dimensional metal-organic framework (MOF) that exhibits strong energetic properties with high thermostability. The compound is synthesized by the hydrothermal method with in situ ligand formation under controlled pH. Structural characterization is carried out by single-crystal XRD, elemental analysis and FTIR. Energetic properties are obtained from TGA and DSC measurements. This novel MOF structure is thermally stable up to 345 C and its heat of detonation is -400$ kJ/g. The measured velocity and pressure of detonation are 4.66 km/s and 9.99 GPa, respectively.
