6,6′-(hydrazine-1,2-diyl)bis(8-nitro-[1,2,4]triazolo[4,3-b]pyridazine-3,7-diamine) (HDP) was designed. HDP exhibits a striking thermal decomposition temperature, indicating its potential to be used as a heat-resistant energetic material.
A series of high-performance 2-(1,2,4-triazole-5-yl)-1,3,4-oxadiazole-based energetic compounds was obtained by a resonance-assisted hydrogen bonding approach.
A mechanistic rationale explaining why aromatic amine substrates with or without resonance-assisted hydrogen bonds (RAHBs) can undergo nitration.
Crystallographic and energetic analyses show how E/Z isomers form distinct supramolecular architectures. Hydrogen bonding and dispersion govern assembly, with energy vector diagrams revealing interaction hierarchies in acyclic systems.
An advanced tetracyclic heat-resistant explosive compound 3 with high thermal stability and good detonation performance was prepared by introducing a high-energy bis(4-nitropyrazole) bridge between two 4H-1,2,4-triazole-3,4-diamine frameworks.
