High proton conductivity at low relative humidity in an anionic Fe-based metal-organic framework

A metal-organic framework, termed VNU-15 (VNU = Vietnam National University), was synthesized and subsequent detailed structural analysis revealed that the crystalline structure adopted the fob topology. Due to integrated sulphate ligands accompanied by hydrogen-bonded dimethylammonium ions that lined the pore channels of VNU-15, the proton conductivity of this material reached 2.90 × 10-2 S cm-1 at 95°C and 60% relative humidity. Remarkably, the high proton conductivity of VNU-15 was maintained under these conditions, without any appreciable loss, for 40 h.
