Novel Multifunctional Samarium-Organic Framework for Fluorescence Sensing of Ag⁺, MnO₄ ^-, and Cimetidine and Electrochemical Sensing of o-Nitrophenol in Aqueous Solutions.

ABSTRACT: A novel Sm-metal-organic framework (MOF) sensor with the molecular formula Sm₈(HDBA)₆·H₂O has been prepared based on a penta-carboxyl organic ligand (H₅DBA = 3,5-di(2',4'-dicarboxylphenyl)benzoic acid) and samarium nitrate under solvothermal conditions. Sm-MOF is characterized by single-crystal X-ray diffraction analysis, elemental analysis, thermogravimetric analysis, and powder X-ray diffraction analysis. Structural analysis shows that the dimer metal units are alternately connected to form a one-dimensional chain, and this chain is connected by the bridging carboxyl oxygen of the ligand H₅DBA to form a two-dimensional double-layer plane, which then expands into a three-dimensional microporous framework.
