Structural variability of rare earth carboxylates based on polydentate carboxylate ligand containing pyridine group

Eu‐based coordination polymer with fluorescence enhancement for Cu2+/prochloraz and quenching for nitrobenzene/pyrimethanil

“…14 Rare-earth coordination polymers linked by flexible carboxylic acids or rigid organic ligands with multiple coordination sites have been extensively reported. 15 For example, 5-(pyridin-3-ylmethoxy) isophthalic acid (3-H 2 pyia) is an organic flexible carboxylate ligand with abundant coordination sites of two carboxyl groups and a pyridine group, and it is easy to construct structurally rich coordination polymers and has been used in the synthesis of rare earth coordination polymers. 16 Li et al used 3-H 2 pyia as the main ligand for the synthesis strategy to prepare six coordination polymers.…”

A 12-Connected [Y4((μ3-OH)4]8+ Cluster-Based Luminescent Metal-Organic Framework for Selective Turn-on Detection of F− in H2O

“…Because lanthanide ions can be considered as hard acids according to Pearson’s theory [ 37 ], the choice of the ligand is of first importance as far as polynuclear hydroxidolanthanide based cluster metal-organic frameworks is concerned. Most of them are built with the classical benzoic multicarboxylate ligands, such as terephthalate [ 16 , 38 , 39 ], 2-hydroxyterephthalic [ 18 ], 2,5-dihydroxyterephthalic, 1,2,3- or 1,3,5-benzenetricarboxylic, 1,2,4,5-benzenetetracarboxylic and 4,4′-biphenyldicarboxylate acid, which are versatile building blocks to obtain various high dimensional lanthanide frameworks due to their variety of bridging abilities [ 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ].…”

Red Fluorescent Eu(TTA)3BIP Complex and Its Application in Blue Light‐Reducing Film

“…The electronic transitions in lanthanide complexes mostly belong to f-f transitions, which can provide sharp emission peaks. [4,5] Moreover, by adjusting or optimizing ligands, the fluorescence intensity can be significantly improved. Eu(III) complexes are usually the preferred choice for manufacturing red light generating devices, as they have the strongest emission characteristic peak near the wavelength of 612 nm.…”

“…Therefore, it is widely used in fields such as electroluminescence, photoluminescence, and thermoluminescence. The electronic transitions in lanthanide complexes mostly belong to f–f transitions, which can provide sharp emission peaks [4,5] . Moreover, by adjusting or optimizing ligands, the fluorescence intensity can be significantly improved.…”
