Two-Dimensional Cr(III)-Based Metal–Organic Framework with Ultrahigh Stability and Superprotonic Conductivity Enabled by Sulfonate Stereochemistry
at 90 °C and 100% RH, which, to the best of our knowledge, is among the highest reported for additive-free proton-conducting 2D MOFs. Owing to inert Cr-O bonds and extensive interlayer hydrogen bonding, TGU-80(Cr) also exhibits exceptional chemical stability from strongly acidic media to 1 M NaOH. This work not only establishes an unprecedented 2D Cr-MOF that combines ultrahigh stability with superprotonic conductivity but also expands the design and synthesis strategies for low-dimensional reticular materials via the green solvent-free route.
