Effective detection of organic/inorganic pollutants, such as antibiotics, nitro-compounds, excessive Fe and MnO , is crucial for human health and environmental protection. Here, a new terbium(III)-organic framework, namely [Tb(TATAB)(H O)]⋅2H O (Tb-MOF, H TATAB=4,4',4''-s-triazine-1,3,5-triyltri-m-aminobenzoic acid), was assembled and characterized. The Tb-MOF exhibits a water-stable 3D bnn framework. Due to the existence of competitive absorption, Tb-MOF has a high selectivity for detecting Fe , MnO , 4-nirophenol and nitroimidazole (ronidazole, metronidazole, dimetridazole, ornidazole) in aqueous through luminescent quenching. The results suggest that Tb-MOF is a simple and reliable reagent with multiple sensor responses in practical applications. To the best of our knowledge, this work represents the first Tb -based MOF as an efficient fluorescent sensor for detecting metal ions, inorganic anions, nitro-compounds, and antibiotics simultaneously.
有效检测有机/无机污染物（如抗生素、硝基化合物、过量的 Fe 和 MnO ）对人类健康和环境保护至关重要。在此，我们组装并表征了一种新型的铽（III）-有机框架，即[Tb(TATAB)(H 2 O)]·2H 2 O（Tb-MOF，H TATAB=4,4',4''-均三嗪-1,3,5-三基三-m-氨基苯甲酸碱）。Tb-MOF 具有稳定的 3D bnn 骨架。由于存在竞争性吸收，Tb-MOF 对水溶液中的 Fe 、MnO 、4-硝基苯酚和硝基咪唑（罗硝唑、甲硝唑、二甲硝唑、奥硝唑）具有高选择性的荧光猝灭检测能力。结果表明，Tb-MOF 是一种简单可靠的试剂，在实际应用中具有多种传感器响应。据我们所知，这是首例将基于 Tb 的 MOF 作为一种高效荧光传感器，用于同时检测金属离子、无机阴离子、硝基化合物和抗生素的研究工作。
