“…As organic building blocks, many diverse types of aromatic carboxylic acids have been applied due to their stability, versatile coordination modes when combined with lanthanide metal nodes, and the ability to act as both H-bond acceptors and donors and assemble supramolecular structures. 6,7,9,[10][11][12][13][14][15][16] Aiming at exploring various aromatic carboxylic acids as main building blocks for the hydro-or solvothermal self-assembly synthesis of functional lanthanide coordination compounds, we have selected 5-fluoronicotinic acid…”

“…The formulated as [Y 4 (OH) 4 (25p) 4 (H 2 O) 3 ].H 2 O and [Y 6 (OH) 8 (25p).5(H 2 O) 2 ] (25p = 2,5-pyridinedicaboxylate) lanthanide–organic frameworks, have been obtained by Abdelbaky and his coauthors as single phases under hydrothermal conditions. While the structure of [Y 6 (OH) 8 (25p).5(H 2 O) 2 ] is based on two independent cuban-like[Y 4 (OH) 4 ] 8+ clusters, which are joined together through Y1 cation leading to the formation of hexanuclear[Y 6 (OH) 8 ] 10+ clusters, which in turn are joined via Y2 cation resulting in infinite inorganic chain, and each chain is interconnected to six adjacent chains through 2,5-pyridinedicaboxylate ligands leading finally to 3D framework [ 34 ]. Interestingly, Liu et al controlled hydrolysis of complexes Cp 2 Ln(η 2 -HBzimt)(THF) 2 , CpLn(η 2 -HBzimt) 2 (THF) and [(Cp 2 Ln)(THF)] 2 (μ-Bzimt) resulting in the same tetranuclear complexes [CpLn(μ 3 -OH)( μ-η 1 : η 2 -HBzimt)] 4 (Ln = Yb, Er, Y), indicating that the hydrolysis selectivity greatly depends on the number of coordinated cyclopentadienyl groups [ 35 ].…”

Fluoride ion (F−) is one of the most hazardous elements in potable water. Over intake of F− can give rise to dental fluorosis, kidney failure, or DNA damage. As a result, developing affordable, equipment-free and credible approaches for F− detection is an important task. In this work, a new three dimensional rare earth cluster-based metal-organic framework assembled from lanthanide Y(III) ion, and a linear multifunctional ligand 3-nitro-4,4′-biphenyldicarboxylic acid, formulated as {[Y(μ3-OH)]4[Y(μ3-OH)(μ2-H2O)0.25(H2O)0.5]4[μ4-nba]8}n (1), where H2nba = 3-nitro-4,4′-biphenyldicarboxylic acid, has been hydrothermally synthesized and characterized through infrared spectroscopy (IR), elemental and thermal analysis (EA), power X-ray diffraction (PXRD), and single-crystal X-ray diffraction (SCXRD) analyses. X-ray diffraction structural analysis revealed that 1 crystallizes in tetragonal system with P4¯21m space group, and features a 3D framework with 1D square 18.07(3)2 Å2 channels running along the [0,0,1] or c-axis direction. The structure of 1 is built up of unusual eight-membered rings formed by two types of {Y4O4} clusters connected to each other via 12 μ4-nba2− and 4 μ3-OH− ligands. Three crystallographic independent Y3+ ions display two coordinated configurations with a seven-coordinated distorted monocapped trigonal-prism (YO7) and an eight-coordinated approximately bicapped trigonal-prism (YO8). 1 is further stabilized through O-H⋯O, O-H⋯N, C-H⋯O, and π⋯π interactions. Topologically, MOF 1 can be simplified as a 12-connected 2-nodal Au4Ho topology with a Schläfli symbol {420·628·818}{43}4 or a 6-connected uninodal pcu topology with a Schläfli symbol {412·63}. The fluorescent sensing application of 1 was investigated to cations and anions in H2O. 1 exhibits good luminescence probing turn-on recognition ability toward F− and with a limit detection concentration of F− down to 14.2 μM in aqueous solution (Kec = 11403 M−1, R2 = 0.99289, σ = 0.0539). The findings here provide a feasible detection platform of LnMOFs for highly sensitive discrimination of F− in aqueous media.

“…Metal-organic frameworks (MOFs), as an important class of advanced functional materials, have received extensive attention due to their great potential application in various research areas, such as gas adsorption/storage [ 1 , 2 , 3 , 4 , 5 ], liquid separation [ 6 ], drug delivery [ 4 , 7 ], and heterogeneous catalysis [ 8 , 9 , 10 ]. Among different classes of MOFs, lanthanide MOFs (LnMOFs) [ 11 , 12 , 13 , 14 , 15 ], which can be synthesized using a wide range of lanthanide cations and organic ligands, have been investigated in the fields of coordination chemistry, inorganic chemistry, and material chemistry, not only for their diverse architectures due to high coordination numbers and large ionic radii of lanthanide cations, but also for the potential applications in the field of luminescence [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 ], because of their increased brightness and emission quantum yield [ 22 , 23 ], and also in magnetism [ 11 , 24 , 25 , 26 , 27 , 28 ]. To obtain functional MOFs, considerable efforts have been made and tremendous progress has been achieved.…”

Metal-organic frameworks assembled from Ln(III), Li(I) BDC = terephthalic acid), were obtained under hydrothermal conditions. The isostructural MS1-6 crystallize in monoclinic P2 1 /c space group. While, in the case of Tb 3+ a mixture of at least two phases was obtained, the former one (MS7a) and a new monoclinic C2/c phase (MS7b). All compounds have been studied by single-crystal and powder X-ray diffraction, thermal analyses (TGA), vibrational spectroscopy (FTIR), and scanning electron microscopy (SEM-EDX). The structures of MS1-6 and MS7a are built up of inorganic-organic hybrid chains. These chains constructed from unusual four-membered rings, are formed by edge-and vertex-shared {LnO 8 } and {LiO 4 } polyhedra through oxygen atoms O3 (vertex) and O6-O7 (edge). Each chain is cross-linked to six neighboring chains through six terephthalate bridges. While, the structure of MS7b is constructed from double inorganic chains, and each chain is, in turn, related symmetrically to the adjacent one through the c glide plane. These chains are formed by infinitely alternating {LiO 4 } and {TbO 8 } polyhedra through (O2-O3) edges to create Tb-O-Li connectivity along the c-axis. Both MS1-6,7a and MS7b structures possess a 3D framework with 1D trigonal channels running along the a and c axes, containing water molecules and anhydrous, respectively. Topological studies revealed that MS1-6 and MS7a have a new 2-nodal 3,10-c net, while MS7b generates a 3D net with unusual β-Sn topology. The photoluminescence properties Eu-and Tb-doped compounds (MS5-6) are also investigated, exhibiting strong red and green light emissions, respectively, which are attributed to the efficient energy transfer process from the BDC ligand to Eu 3+ and Tb 3+ .
