Planar Bis(1,3,4-Oxadiazole) Bridging toward High-Energy and Low-Sensitivity Tetracyclic Compounds
Abstract A planar bis(1,3,4-oxadiazole) bridging strategy was developed to access rigid, extended-conjugated tetracyclic energetic compounds. Incorporation of this bridge into two distinct energetic scaffolds afforded 4 and 7. Single-crystal X-ray diffraction revealed a nearly planar bis(1,3,4-oxadiazole) bridge in both compounds, accompanied by extended π-electron delocalization across the molecular frameworks. Compound 4 showed enhanced thermal and mechanical stability, while 7 combined improved energetic performance with increased stability.
