Series of Metal Organic Frameworks Assembled from Ln(III), Na(I), and Chiral Flexible-Achiral Rigid Dicarboxylates Exhibiting Tunable UV–vis–IR Light Emission

Two series of isoreticular chiral metal–organic frameworks assembled from Ln­(III) (Ln = Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb), Na­(I), and chiral flexible-achiral rigid dicarboxylate ligands, formulated as [NaLn­(Tart)­(BDC)­(H2O)2] (S1) and [NaLn­(Tart)­(biBDC)­(H2O)2] (S2) (H2Tart = tartaric acid; H2BDC = terephthalic acid; H2biBDC = biphenyl-4,4′-dicarboxylic acid), were obtained as single phases under hydrothermal conditions. The compounds have been studied by single-crystal and powder X-ray diffraction, thermal analyses (TG-MS and DSC), vibrational spectroscopy (FTIR), scanning electron microscopy (SEM-EDX), elemental analysis, and X-ray thermodiffractometry. The catalytic activity has been also investigated. The photoluminescence properties of selected compounds have been investigated, exhibiting room temperature tunable UV–vis–IR light emission.
