Microporous lanthanide metal-organic frameworks

Abstract

Microporous metal-organic frameworks (MOFs) based on lanthanide metal ions or clusters represent a group of porous materials, featuring interesting coordination, electronic, and optical properties. These attractive properties in combination with the porosity make microporous lanthanide MOFs (Ln-MOFs) hold the promise for various applications. This review is to provide an overview of the current status of the research in microporous Ln-MOFs, and highlight their potential as types of multifunctional materials for applications in gas/solvent adsorption and separation, luminescence and chemical sensing and catalysis.

New Microporous Lanthanide Organic Frameworks. Synthesis, Structure, Luminescence, Sorption, and Catalytic Acylation of 2-Naphthol

“…The solvent-accessible volume of the channels is equal to 2060 Å 3 /unit cell, which constitutes 48% of the unit cell volume. (1). Extended view of the asymmetric part and coordination environment around La in 1 along with the atom labelling scheme and thermal ellipsoids at the 40% probability level.…”

“…It is known that lanthanides often exhibit luminescence properties [1,16,52]. In order to study the luminescence properties of the synthesized frameworks, the fluorescence spectra of Ln-MOFs (1, 2, 3, and 4) as well as ligand H 3 L were recorded in solid state (powder) at room temperature.…”

“…Metal-organic frameworks (MOFs) form a class of porous materials that have been intensively studied in the last decade [1][2][3][4][5][6]. MOFs provide diverse and easily modifiable architectures and topologies and play important roles in synthetic chemistry [7], catalysis [2,[8][9][10], molecular separation [11], magnetism [12,13], optics [14,15] possess luminescence [16,17], and are used as potential drug delivery carriers [18][19][20].…”

Rare earth based nanostructured materials: synthesis, functionalization, properties and bioimaging and biosensing applications

“…Some of the organic ligands most frequently used are shown in Figure 2. A more extended and comprehensive list of the different organic ligands used for the synthesis of RE-based MOFs can be found in a review by Chen and Ma [27]. MOFs can either be based on RE cations or serve as host structures, in which the RE cations can be incorporated into the connectivity centers or inside the pores of the MOF.…”

“…Ln-containing luminescent MOFs have been recently the subject of much attention because of their promising applications in several fields, including biotechnology. They can either be built from Ln cations or serve as host structures, in which the Ln cations can be incorporated into the connectivity centers or inside the pores of the MOF [26,27]. Their highly porous and oriented structures, which allow them to accommodate many different cargoes, and their intrinsic biodegradability make them interesting materials for biomedical applications, especially for sensing and delivery [28].…”
