Highly Selective Luminescent Sensing of Fluoride and Organic Small-Molecule Pollutants Based on Novel Lanthanide Metal–Organic Frameworks
Abstract
Two novel isostructural lanthanide metal-organic frameworks (Ln-MOFs), [Ln2(BPDC)(BDC)2(H2O)2]n (Ln = Eu (1) and Tb (2)), have been successfully synthesized via a mixed ligand approach using 2,2'-bipyridine-3,3'-dicarboxylic acid (H2BPDC) and 1,4-benzenedicarboxylic acid (H2BDC) under hydrothermal conditions. Structural analysis shows that two lanthanide ions are 4-fold linked by two κ(1)-κ(1)-μ2 carboxylates from BDC(2-) and the other two κ(2)-κ(1)-μ2 carboxylates from BPDC(2-) to form a binuclear core. The binuclear units are further connected by BDC(2-) and BPDC(2-) to build a three-dimensional framework possessing tfz-d topology with the short (Schläfli) vertex symbol {4(3)}2{4(6)·6(18)·8(4)}. Moreover, isostructural doped Ln-MOFs [Eu(2x)Tb2(1-x)(BPDC)(BDC)2(H2O)2]n (x = 0.1 (1a), 0.3 (1b), 0.5 (1c), 0.7 (1d), and 0.9 (1e)) were also successfully synthesized. Thermal gravimetric analyses (TGA) reveal high thermal stability of these Ln-MOFs. Luminescent measurements indicate that the characteristic sharp emission bands of Eu(3+) and Tb(3+) ions are simultaneously observed in 1a-e. Further luminescent studies reveal that 1, 2, and 1a not only display a high-sensitivity sensing function with respect to fluoride but also exhibit significant solvent-dependent luminescent response to small-molecule pollutants, such as formaldehyde, acetonitrile, and acetone.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
