Photoluminescent Metal–Organic Frameworks for Gas Sensing
Luminescence of porous coordination polymers (PCPs) or metal-organic frameworks (MOFs) is sensitive to the type and concentration of chemical species in the surrounding environment, because these materials combine the advantages of the highly regular porous structures and various luminescence mechanisms, as well as diversified host-guest interactions. In the past few years, luminescent MOFs hav...
متن کاملBook review of “Lanthanide metal-organic frameworks”
Metal-organic frameworks (MOFs) are chemical systems comprising organic molecules coordinated to metal ions or clusters to form one-, two-, or three-dimensional structural arrangement (Figure 1). The use of lanthanide (Ln) ions results in a specific class of Ln-MOFs possessing unique physico-chemical properties owing to a large atomic magnetic moment, strong spin-orbital coupling, high coordina...
متن کاملTowards multifunctional lanthanide-based metal-organic frameworks.
We report the synthesis, structure and physicochemical attributes of a new holmium(III)-based metal-organic framework whose 3D network structure gives rise to porosity; the reported structure-type can be varied using a range of different lanthanide ions to tune the photophysical properties and produce ligand-sensitised near-infrared (NIR) and visible light emitters.
متن کاملSynthesis, Structures and Luminescence Properties of Metal-Organic Frameworks Based on Lithium-Lanthanide and Terephthalate
Metal-organic frameworks assembled from Ln(III), Li(I) and rigid dicarboxylate ligand, formulated as [LiLn(BDC)2(H2O) ̈ 2(H2O)] (MS1-6,7a) and [LiTb(BDC)2] (MS7b) (Ln = Tb, Dy, Ho, Er, Yb, Y0.96Eu0.04, Y0.93Tb0.07, and H2BDC = terephthalic acid), were obtained under hydrothermal conditions. The isostructural MS1-6 crystallize in monoclinic P21/c space group. While, in the case of Tb3+ a mixture ...
متن کاملSynthesis, Structure and Properties of Lanthanide-Organic Frameworks with Imidazolylmethylisophthalate Ligands
Three new lanthanide-organic frameworks {[Ln(L)(OClO3)(H2O)]·0.5H2O}n [Ln = Sm (1), Eu (2), Er (3)] have been prepared by hydrothermal reactions of the corresponding lanthanide oxide (Ln2O3), silver perchlorate (AgClO4) and 5-(imidazol-1-ylmethyl)isophthalic acid. The complexes have been characterized by single-crystal and powder X-ray diffraction, IR spectroscopy, and elemental analyses. In 1–...
