Both materials contain the same phosphonato-sulfonate linker molecule, but have clearly different crystal structures, which has a strong effect on proton conductivity. In the Mg-based coordination network, dangling sulfonate groups are part of an extended hydrogen bonding network, facilitating a “proton hopping” with low activation energy; the material shows a moderate proton conductivity. In the Pb-based metal-organic framework, in contrast, no extended hydrogen bonding occurs, as the sulfonate groups coordinate to Pb<jats:sup>2+</jats:sup>, without forming hydrogen bonds; the proton conductivity is much lower in this material.</jats:p> Beilstein Institut2022 eng Electrical and Electronic EngineeringGeneral Physics and AstronomyGeneral Materials Science 2190-428610.3762/bjnano.13.36 13437-443 Javed A, Steinke F, Wöhlbrandt S, Bunzen H, Stock N, Tiemann M.
