“…16−18 Nitrogen-rich heterocyclic compounds have garnered significant attention from researchers due to their distinct coordination modes, high nitrogen content, and promising energetic properties. 19 Since the energy of nitrogen-rich compounds comes from the nitrogen produced by N�N and N−N bonds, the design and synthesis of nitrogen-rich tetrazole rings and their derivatives is a key approach to the development of environmentally friendly materials. 20 To date, numerous nitrogen-rich tetrazole ring ligands have been employed in the synthesis of EMOFs.…”

In recent years, energetic metal−organic frameworks (EMOFs) have gained significant attention in the field of energetic materials research. In this paper, we synthesized MOFs by reacting 1,5′-bitetrazolate-2N-oxide with Co(NO 3 ) 2 , Zn(NO 3 ) 2 , Cu(NO 3 ) 2 , and AgNO 3 , respectively. The resulting materials were characterized by using single-crystal X-ray diffraction. EMOFs 2 and 3 exhibited a 1D chain structure, while EMOF 4 displayed a 2D structure and EMOF 5 possessed a 3D framework structure. The structures, thermal stability, thermal decomposition kinetics, and energetic properties of the four EMOFs were thoroughly analyzed and characterized in this study. The results showed that the synthesized EMOFs have a high density (1.933−3.010 g cm −3 ). Among these EMOFs, EMOF 2 displayed the highest decomposition temperature (T d = 182 °C). Moreover, EMOF 5 exhibited superior energy properties (D = 7748 m s −1 ; P = 36.3 Gpa) and demonstrated excellent catalytic effects on the decomposition of ammonium perchlorate.
