摘要	氟啶胺（Fluazinam, FLU）和苦味酸（picric acid, PA）是两种典型的有机化合物，具有高毒性和生物蓄积性，会造成环境污染，影响人体健康。本文基于课题组前期研究参照文献制备了咪唑功能化材料HBU-167（Ba(II)-MOF），并将其应用于荧光检测氟啶胺和苦味酸。在氟啶胺检测方面，其检出限（Limit of Detection, LOD）为7.5 μM，当氟啶胺的浓度增加到909 μM时，荧光猝灭率达到95.65％，通过Stern-Volmer方程计算得到猝灭常数为22.00 M−1；通过紫外-可见光谱法等检测手段，推测其检测机理为动态荧光猝灭，HBU-167与氟啶胺之间存在竞争吸收。在苦味酸检测方面，其LOD为0.46 μM，当苦味酸的浓度增加到56.604 μM时，通过Stern-Volmer方程计算得到猝灭常数为4.2 × 104 M−1；通过荧光寿命及荧光量子产率、吸附能和紫外-可见光谱等检测手段，推测其检测机理为静态荧光猝灭。
Abstract	Fluazinam (FLU) and picric acid (PA) are two typical organic compounds with high toxicity and bioaccumulation, which will cause environmental pollution and affect human health. In this paper, imidazole functional material HBU-167 (Ba(II)-MOF) was prepared based on the previous research references of our research group, and it was applied to the fluorescence detection of fluridine and picric acid. For the Detection of fluridine, the Limit of Detection (LOD) was 7.5 μM. When the concentration of fluridine increased to 909 μM, the fluorescence quenching rate reached 95.65%, and the quenching constant was 22.00 M−1 calculated by Stern-Volmer equation. Through UV-VIS spectroscopy and other detection methods, it is speculated that the detection mechanism is dynamic fluorescence quenching, and there is competitive absorption between HBU-167 and fluridine. In the detection of picric acid, the LOD is 0.46 μM, and when the concentration of picric acid increases to 56.604 μM, the quenching constant calculated by Stern-Volmer equation is 4.2 × 104 M−1. By means of fluorescence lifetime, fluorescence quantum yield, adsorption energy and UV-VIS spectrum, the detection mechanism is inferred to be static fluorescence quenching.
