N2 - 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)x,
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.
