A novel Eu-MOF sensor, named as [Eu₅(DBA)₃]_n (1), has been prepared based on 3,5-di(2′,4′-dicarboxylphenyl) benozoic acid (H₅DBA) and europium nitrate under solvothermal condition. Structural analysis shows that the binuclear and polynuclear inorganic building untis to form stable microporous structure based on the wholly deprotonated DBA ligands. The microporous structure of 1 has been verified by the gas adsorption experiment of N₂. Fluorescence studies show that Eu-MOF can detect acetone molecules, Cu²⁺ ion and Cr₂O₇²⁻ anion with high sensitivity and selectivity, and can also be used for electrochemical detection of exposed 2,4,6-trinitrophenol (TNP) in water. The high selective and sensitive detection ability of complex 1 might make it a potential multifunctional sensor in the future.

基于3,5-二（2'，4'-二羧基苯基）苯甲酸（H ₅ DBA）和euro，制备了一种名为[Eu ₅（DBA）₃ ] _n（1）的新型Eu-MOF传感器。溶剂热条件下的硝酸盐。结构分析表明，基于全去质子化的DBA配体，双核和多核无机建筑无法形成稳定的微孔结构。N ₂的气体吸附实验已验证了1的微孔结构。荧光研究表明Eu-MOF可以检测丙酮分子，Cu ²⁺离子和Cr ₂ O ₇ ^2-具有高灵敏度和选择性的阴离子，也可用于电化学检测水中暴露的2,4,6-三硝基苯酚（TNP）。配合物1的高选择性和灵敏检测能力可能使其成为未来的潜在多功能传感器。
