Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>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, [Zr₆O₄(OH)₄(L1)_2.6(L2)_0.4]⋅(solvent)_{<italic>x</italic>}, was formed that has three‐dimensional crystalline permanent porosity with a surface area of over 4000 m² g⁻¹ that persists after immersion in water. These properties are not accessible for the isostructural phases made from the separate single linkers.</p> </abstract>
