Synthesis, structure and proton conductivity of a metal-organic framework with rich hydrogen-bonds between the layers

A new MOF material with rich H-bond network is synthesized by using l-malic acid and 5-methyl-1H-tetrazole as dual ligands. The proton conductivity was 1.33 × 10− 5 S cm− 1 at 60 °C under 95% RH, which indicates that this material is a potential candidate material for proton conductivity.307
