摘要
镧系元素金属有机框架(Ln-MOFs)因其优异的光学特性而在传感领域具有独特的优势。在本研究中,我们合成了带有酰胺基团的二羧酸配体,并通过溶热法成功合成了分子式为 C42H31EuN4O10 的新型二维(2D)MOF(Eu-MOF)。单晶 X 射线衍射显示,酰胺基团暴露在二维配位层的外部,可通过氢键相互作用识别特定分子。配体的 "天线效应 "使 Eu-MOF 能够发出以 "f-f "转变为特征的强荧光。进一步的研究表明,Eu-MOF 可用作选择性检测苯甲醛和 Fe3+ 的双功能荧光探针。通过粉末 X 射线衍射(PXRD)分析、紫外-可见光谱分析、荧光寿命测量和密度泛函(DFT)理论计算,对其传感机制进行了详细分析。该设计和研究可为后续相关工作提供参考。
A Novel 2D Eu-MOF as a Dual-Functional Fluorescence Sensor for Detection of Benzaldehyde and Fe3+
Lanthanide metal-organic frameworks (Ln-MOFs) have unique advantages in sensing due to their excellent optical properties. In this study, we synthesized a dicarboxylic acid ligand with amide groups and successfully synthesized a novel two-dimensional (2D) MOF with the molecular formula C42H31EuN4O10 (Eu-MOF) by solvothermal method. Single-crystal X-ray diffraction showed that amide groups are exposed on the outside of the two-dimensional coordination layer, with the possibility of recognizing specific molecules through hydrogen bonding interactions. The ligand's "antenna effect" enables Eu-MOF to emit a strong luminescence characterized by the "f-f" transition. Further studies have revealed that Eu-MOF could be used as a bifunctional fluorescent probe for the selective detection of benzaldehyde and Fe3+. The sensing mechanism has been analyzed in detail through powder X-ray diffraction (PXRD) analysis, UV-vis spectroscopy, fluorescence lifetime measurement, and density functional (DFT) theory calculation. This design and research can provide a reference for subsequent related work.
