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 (HL) containing tetrazole and carbolxylate moieties was employed for the synthesis of a two-dimensional (2D) lanthanide MOF [La(HL)(DMF)(NO)] (DMF = ,-dimethylformamide) () under solvothermal condition. The fluorescent sensing application of was investigated. exhibits high sensitivity recognition for antibiotic nitrofurantoin (K: 3.0 × 10 M and detection limit: 17.0 μM) and amino acid l-tyrosine (K: 1.4 × 10 M 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.
金属-有机框架（MOFs）因其在许多不同化学和材料领域的广泛应用而得到了快速发展。在这项工作中，使用了一种多齿建筑块 5-(4-(四唑-5-基)苯基）-间苯二甲酸（HL），其中含有四唑和羧酸酯部分，用于合成二维（2D）镧系 MOF [La(HL)(DMF)(NO)]（DMF =,-二甲基甲酰胺）()在溶剂热条件下。研究了 的荧光传感应用。 对抗生素呋喃妥因（K：3.0×10 M，检测限：17.0 μM）和氨基酸 l-酪氨酸（K：1.4×10 M，检测限：3.6 μM）具有高灵敏度识别能力。这项工作为 2D MOFs 提供了一个可行的检测平台，用于高度敏感地区分抗生素和氨基酸。
