Abstract:
Two new high-energy metal-organic frameworks (HE-MOFs), {Ag2(DNMAF)(H2O)2}n (1) and {Ag2(DNMAF)}n (2) were prepared using potassium 4,4'-bis(dinitromethyl)-3,3'-azofurazanate (K2DNMAF) in a self-assembly strategy. Compound 1 exhibits a 3D HE-MOF structure with coordinated water molecules. Compound 2 exhibits compact solvent-free 3D HE-MOFs. Both compounds show good thermostability (decomposition temperature (Td) of 211 and 218 °C) and superior detonation velocities (D) of 9673 m s-1 and 10 242 m s-1, detonation pressures (P) of 50.01 GPa and 58.30 GPa, and heat of detonation (Q) of 1.95 kcal g-1 and 2.19 kcal g-1, respectively, which are even higher than those of RDX and HMX.
