We prepared a series of 1,3,6,8-tetrakis(arylethynyl)pyrenes with donor or acceptor substituents and investigated their photophysical properties. Solvent polarity hardly affected on the UV/vis spectra of all of the tetrakis(arylethynyl)pyrenes used in thi

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(e-thyne-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.
