Fabrication of two 3D Ln-MOFs as highly sensitive luminescent sensors for Fe3+ and Cr3+ ions
Two new isostructural lanthanide(III)−metal organic frameworks (Ln-MOFs), namely [Ln2(FDA)3(TMS)2(H2O)2]·H2O (Ln = Eu 1 and Tb 2, H2FDA = 2,5-furandicarboxylic acid, TMS = tetramethylene sulfone), have been synthesized and characterized. Single-crystal X-ray diffraction analysis reveals that both Ln-MOFs exhibit three-dimensional structures crystallizing in the monoclinic C2/c space group. Luminescent sensing studies indicate that 1 and 2 possess commendable capabilities for detecting Fe3+ and Cr3+, with low detection limits of 20.00 nM and 43.41 nM for 1 and 66.10 nM and 0.37 μM for 2, respectively. Furthermore, the investigation into the mechanism revealed the quenching of Fe3+ can be ascribed to the dual effects of inner filter effect (IFE) and the static quenching. Conversely, the dynamic quenching mechanism has played a predominant role during the sensing process of Cr3+.
