Solvothermal Preparation of a Lanthanide Metal-Organic Framework for Highly Sensitive Discrimination of Nitrofurantoin and <span style="font-variant: small-caps">l</span>-Tyrosine
Abstrak
Metal-organic frameworks (MOFs) have been rapidly developed for their broad applications in many different chemistry and materials fields. In this work, a multi-dentate building block 5-(4-(tetrazol-5-yl)phenyl)-isophthalic acid (H<sub>3</sub>L) containing tetrazole and carbolxylate moieties was employed for the synthesis of a two-dimensional (2D) lanthanide MOF [La(HL)(DMF)<sub>2</sub>(NO<sub>3</sub>)] (DMF = <i>N</i>,<i>N</i>-dimethylformamide) (<b>1</b>) under solvothermal condition. The fluorescent sensing application of <b>1</b> was investigated. <b>1</b> exhibits high sensitivity recognition for antibiotic nitrofurantoin (K<sub>sv</sub>: 3.0 × 10<sup>3</sup> M<sup>−1</sup> and detection limit: 17.0 μM) and amino acid <span style="font-variant: small-caps;">l</span>-tyrosine (K<sub>sv</sub>: 1.4 × 10<sup>4</sup> M<sup>−1</sup> and detection limit: 3.6 μM). This work provides a feasible detection platform of 2D MOFs for highly sensitive discrimination of antibiotics and amino acids.
