The synthesis of metal–organic frameworks with large three‐dimensional channels that are permanently porous and chemically stable offers new opportunities in areas such as catalysis and separation. Two linkers (L1=4,4′,4′′,4′′′‐([1,1′‐biphenyl]‐3,3′,5,5′‐tetrayltetrakis(ethyne‐2,1‐diyl)) tetrabenzoic acid, L2=4,4′,4′′,4′′′‐(pyrene‐1,3,6,8‐tetrayltetrakis(ethyne‐2,1‐diyl))tetrabenzoic acid) were used that have equivalent connectivity and dimensions but quite distinct torsional flexibility. With these, a solid solution material, [Zr 6 O 4 (OH) 4 (L1) 2.6 (L2) 0.4 ]⋅(solvent) x , was formed that has three‐dimensional crystalline permanent porosity with a surface area of over 4000 m 2 g −1 that persists after immersion in water. These properties are not accessible for the isostructural phases made from the separate single linkers.
