Journal ArticleDOI
Syntheses, structures, near-infrared and visible luminescence, and magnetic properties of lanthanide-organic frameworks with an imidazole-containing flexible ligand.
TL;DR: The single-crystal X-ray diffraction analysis revealed that six complexes are isomorphous and isostructural and that the dinuclear molecules are further connected by hydrogen bonds and pi-pi interactions, resulting in 3D channel-like structures.
Journal ArticleDOI
Syntheses, structures, and luminescent and magnetic properties of novel three-dimensional lanthanide complexes with 1,3,5-benzenetriacetate.

TL;DR: Five novel lanthanide complexes with the formulas H3bta = 1,3,5-benzenetriacetic acid, in which the bta3- ligands adopt different coordination modes, showed strong luminescence upon excitation, and their luminescent decay curves fit well with single exponential decays.
Journal ArticleDOI
Interpenetrating and Self-Penetrating Zinc(II) Complexes with Rigid Tripodal Imidazole-Containing Ligand and Benzenedicarboxylate
TL;DR: In this article, the photoluminescence and nonlinear optical properties of Zn(II) metal-organic frameworks are investigated, and the influences of reaction temperature and counteranion on the structures of the complexes are discussed.
Journal ArticleDOI
Self-assembly of frameworks with specific topologies: construction and anion exchange properties of M3L2 architectures by tripodal ligands and silver(I) salts.
TL;DR: The results demonstrate that the molecular M3L2 type cage can act as a host for anions and provide a nice example of supramolecular architectures with interesting properties and possible applications.
Journal ArticleDOI
Syntheses, structures, and photoluminescence properties of metal(II) halide complexes with pyridine-containing flexible tripodal ligands.
TL;DR: Seven coordination compounds synthesized by the reactions of ligands can adopt different conformations and thus can form complexes with varied structures, and the photoluminescence properties of the complexes showed blue emissions in solid state at room temperature.
