Influence of Ligand Environment Stoichiometry on NIR-Luminescence Efficiency of Sm3+, Pr3+ and Nd3+ Ions Coordination Compounds
2023 в печати · ARTICLE · en
Six new complexes of the ligand HQcy (-4-(cyclohexanecarbonyl)-5-methyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one) and Ln3+ ions with emission in the near-infrared (Nd3+) or visible and near-infrared (Sm3+, Pr3+) spectral regions were synthesized and characterized using various methods, including single crystal X-ray diffraction. The study demonstrated that both tris complexes [LnQcy3(H2O)(EtOH)] and tetrakis-acids [H3O][LnQcy4] can be synthesized by varying the synthetic conditions. The photochemical properties of the complexes were investigated experimentally and theoretically using various molecular spectroscopy techniques and Judd–Ofelt theory. The objective was to quantitatively and qualitatively disclose the influence of complex stoichiometry on its luminescence properties. The study showed that the addition of an extra ligand molecule (in the tetrakis species) increased molar extinction by up to 2 times, affected the shape of photoluminescence spectra, especially of the Pr3+ complex, and increased the quantum yield of the Sm3+ complex by up to 2 times. The results obtained from this study provide insights into the luminescent properties of lanthanide coordination compounds, which are crucial for the design and development of novel photonic materials with tailored photophysical properties.
New Carboxylate Anionic Sm-MOF: Synthesis, Structure and Effect of the Isomorphic Substitution of Sm3+ with Gd3+ and Tb3+ Ions on the Luminescent Properties
2022 · ARTICLE · en
Two new compounds, namely {(NMe2H2)}[Ln(TDA)(HCOO)] 0.5H2O, Ln = Sm3+ (Sm-TDA) and Gd3+ (Gd-TDA), where TDA3− is the anion of 1H-1,2,3-triazole-4,5-dicarboxylic acid (H3TDA), were synthesized by the solvothermal method in a DMF:H2O mixture. According to single-crystal X-ray diffraction data, the compounds are 3d-MOFs with an anionic lattice and dimethylammonium cations occupying part of the cavities. Based on these compounds, two series of mixed-metal complexes, [NMe2H2][SmxLn1-x(TDA)(HCOO)], (x = 0.9 (Sm0.9Ln0.1-TDA), x = 0.8 (Sm0.8-Ln0.2-TDA)...Sm0.02Ln0.98-TDA, Ln = Tb, Gd), were also obtained and characterized by powder XRD. The luminescent properties of the compounds were studied and it was shown that the resulting compounds are two- or three-component emitters with the possibility of fine color tuning by changing the intensities of fluorescence and phosphorescence of the ligand, as well as the luminescence of Sm3+ and Tb3+ f-ions.

Novel pyrazole-based carboxylate ligand as a building block for assembling lanthanides in luminescent 2D and 3D MOFs
2022 · ARTICLE · en
New pyrazole-based carboxylic ligand 1-(carboxymethyl)-1H-pyrazole-3,5-dicarboxylic acid (H3L) as well as its lanthanide complexes [LnL(H2O)2]n, Ln = La (1), Ce (2), Pr (3), Nd (4), Sm (5), Eu (6), Gd (7), Tb (8) and [LnL(H2O)]n, Ln = Dy (9), Ho (10), Er (11), Tm (12), Yb (13), Lu (14) have been prepared and studied. Compounds 1–8 represent a 3D polymer structure while 9–14 are 2D-polymers. Lanthanide-centered luminescence of compounds 4–9 is studied in detail. It is shown that high energy triplet level of H3L ligand (27100 cm−1) is able to sensitize not only the yellow-green luminescence of Tb3+ and Dy3+ ions, but also the red-orange luminescence of Sm3+ and Eu3+. NIR-luminescence of the neodymium complex 4 is possible upon direct excitation through the f-f transition of the Nd3+ ion.

Lanthanide azolecarboxylate compounds: Structure, luminescent properties and applications
2021 · ARTICLE · en
The unique optical and magnetic properties of lanthanide ions (Ln), like a gem, need the right faceting and the right setting. Azole carboxylic acids provide a unique platform for driving the structure of complex compounds ranging in dimensions from 0-D (molecular complexes) to 1-D, 2-D polymers and 3-D MOF (Metal Organic Framework) structures. The peculiarity of azolecarboxylate ligands is that numerous possible coordination fashions, including both carboxyl groups and nitrogen atoms, on the one hand, open up almost unlimited possibilities for obtaining materials with desired properties, for example, luminescent sources and sensors, molecular magnets, catalysts and materials for gas sorption and separation. Several coordination modes, dependent on the reaction conditions, make the structural diversity of lanthanide carboxylates difficult to predict and require systematic analysis. Our analysis is critical to produce efficient and advanced materials. This review describes and systematizes data on both synthesis and structure and functional properties of pyrazole-, imidazole-, 1,2,3-triazole, 1,2,4-triazole- and tetrazole-carboxylates of lanthanide metals and evaluates the achievements in this area of coordination chemistry. The author's view on the future of the chemistry of lanthanides azole carboxylates and possible new applications in materials science is also presented.
Mono- and Mixed Metal Complexes of Eu3+, Gd3+, and Tb3+ with a Diketone, Bearing Pyrazole Moiety and CHF2-Group: Structure, Color Tuning, and Kinetics of Energy Transfer between Lanthanide Ions
2021 в печати · ARTICLE · en
Three novel lanthanide complexes with the ligand 4,4-difluoro-1-(1,5-dimethyl-1H-pyrazol-4-yl)butane-1,3-dione (HL), namely [LnL3(H2O)2], Ln = Eu, Gd and Tb, were synthesized, and, according to single-crystal X-ray diffraction, are isostructural. The photoluminescent properties of these compounds, as well as of three series of mixed metal complexes [EuxTb1-xL3(H2O)2] (EuxTb1-xL3), [EuxGd1-xL3(H2O)2] (EuxGd1-xL3), and [GdxTb1-xL3(H2O)2] (GdxTb1-xL3), were studied. The EuxTb1-xL3 complexes exhibit the simultaneous emission of both Eu3+ and Tb3+ ions, and the luminescence color rapidly changes from green to red upon introducing even a small fraction of Eu3+. A detailed analysis of the luminescence decay made it possible to determine the observed radiative lifetimes of Tb3+ and Eu3+ and estimate the rate of excitation energy transfer between these ions. For this task, a simple approximation function was proposed. The values of the energy transfer rates determined independently from the luminescence decays of terbium(III) and europium(III) ions show a good correlation.
Synthesis, phosphorescence and luminescence properties of novel europium and gadolinium tris-acylpyrazolonate complexes
2020 · ARTICLE · en
Two new lanthanide (III) complexes, namely [Ln(QCy)3(H2O)] (Ln = Eu (1), Gd (2); HQCy = 1-phenyl-3-methyl-4-cyclohexylcarbonyl-pyrazol-5-one), have been obtained by reaction of corresponding Ln(NO3)3·xH2O with excess of HQCy and MOH, M = Li, Na, K or Cs. Unexpectedly, formation of the [Ln(QCy)4]− species was not observed, also when the reaction was carried out in ligand excess and by varying reaction conditions and molar ratios. [Eu(QCy)3(H2O)] (1) has been structurally characterized by single crystal X-ray study. The crystal structure of 1 is based on molecular [Eu(QCy)3(H2O)] moieties connected by OH…N hydrogen bonds into 1D-chain. Phosphorescence spectra of 2 allowed to determine the very high energy of the triplet level of the ligand (QCy) 23,640 cm−1, which correlates well with the calculated value of 24,040 cm−1. Weak luminescence of the europium species 1 is observed even at room temperature.
