Fig. 6. (a) Adsorption isotherms for water in MFM-510, -511, and -512. Desorption isotherms are shown in ESI† for clarity. (b) Relationship between water capacity and proton conductivity for MFM-510, -511, and -512 and a selection of MOFs in literature. aImpedance measurements at high humidity and room temperature, full details in Table S4.† bWater capacity at the RH of the impedance data. cWater uptake assessed by volumetric or gravimetric analysis.
