| Abstract: Four lanthanide-organic frameworks (LOFs), [LnL1.5(DMA)]n (Ln=Eu (1), Gd (2), Tb (3), Dy (4); H2L=2,2'-dinitro-4,4'-biphenyldicarboxylic acid, DMA=N,N-dimethylacetylamide), have been prepared by the solvo-thermal reaction of H2L and Ln(NO3)3·6H2O. Their structures have been characterized by elemental analyses, IR, TGA, single-crystal and powder X-ray diffraction (XRD) studies. Crystal structure analyses show that LOFs 1~4 crystallize in the monoclinic system with C2/c space group. LOFs 1~4 are isomorphous and possess a binodal (3,8)-connected three-dimensional (3D) topology network. All the LOFs exhibit high thermal stabilities (Td>322 ℃). Furthermore, 1 displays characteristic luminescence of Eu(Ⅲ) ion while 3 only shows the emission peak of the L2- ligand. |
