Energetic isostructural metal imidazolate frameworks with a bridging dicyanamide linker towards high-performance hypergolic fuels

Abstract

The design and development of advanced hypergolic metal-organic frameworks (HMOFs) for space exploration has attracted wide attention in recent years. However, enhancing the energy densities and elucidating the relationship between...

Nitrate anions embedded in rigid and cationic 3D energetic MOFs constructed by the chelating ligand towards insensitive energetic materials

“…Energetic metal–organic frameworks (EMOFs) have garnered significant attention from researchers due to their abundant architectures, excellent heats of detonation, good thermal resistance, and notable mechanical robustness. 27–32 For instance, Chen and co-workers employ a multinuclear Ag( i )-cluster to construct EMOF [Ag 7 (tza) 3 (Htza) 2 (H 2 tza)(H 2 O)] n (H 2 tza = 1 H -tetrazole-5-acetic acid), which is endowed with an exceptionally high energy content (Δ f H ° = 8930.22 ± 0.61 kJ mol −1 ) and insensitive to mechanical stimulation (IS > 40 J,FS > 360 N). 33 To further augment the energy densities of EMOFs, a straightforward and efficient approach is the incorporation of energetic anions, such as NO 3 − and ClO 4 − , into the EMOFs.…”
