The selective recognition and luminescence sensing demonstrated in yttrium - Organic framework

Abstract A new yttrium metal-organic framework was synthesized by using 2,5-furandicarboxylic acid as ligand under hydrothermal conditions. The crystal structures and stability of MOF were characterized by X-ray Diffraction and Thermogravimetric Analyzer, respectively. In particular, Y-MOF exhibits sensitive and highly selective detection for Cu2+ ions, the detection limit can be as low as 0.1 μg/ml. Moreover, Y-MOF also exhibits high selectivity for small molecules such as nitrobenzene and o-chlorophenol and the detection limit are 5 mg/L and 10 mg/L, respectively. The luminescent behavior of Y-MOF signify a promising use as fluorescent probe for sensing of metal ions and small molecules.
