Fast and efficient detection of pollutants in the food or wastewater is an urgent need for protecting human health and ecological environment. Herein, a luminescent Zr(IV)-MOF (HBU-20) has been conveniently synthesized. It could be used as a fluorescent probe for detection of vanillin, CrO, and CrO in aqueous medium. All the fluorescence response time is less than 10 s and the detection limits of vanillin, CrO and CrO achieve 0.38 μM, 0.065 μM and 0.0089 μM, respectively. Interestingly, common anions, cations and amino acids in the solution can not affect the fluorescence detection. Meanwhile, the fluorescence detection process can be successfully implemented even under strong acid or strong alkaline conditions. Further research shows that the inner filter effect (IFE) plays a major role in the sensing process. The rapid and sensitive fluorescence responses indicate that the compound is a promising multifunctional probe for sensing toxic substance. The results can provide an important reference for the design of new fluorescent probes.
快速、高效地检测食品或废水中的污染物对于保护人类健康和生态环境至关重要。在此，我们方便地合成了一种发光 Zr(IV)-MOF（HBU-20）。它可用作荧光探针，用于检测水相中香草醛、CrO 和 CrO。所有荧光响应时间均小于 10 s，香草醛、CrO 和 CrO 的检测限分别达到 0.38 μM、0.065 μM 和 0.0089 μM。有趣的是，溶液中的常见阴离子、阳离子和氨基酸不会影响荧光检测。同时，即使在强酸或强碱条件下，荧光检测过程也能顺利进行。进一步的研究表明，内滤效应（IFE）在传感过程中起主要作用。该化合物具有快速、灵敏的荧光响应，表明其是一种有前途的多功能有毒物质传感探针。该结果可为新型荧光探针的设计提供重要参考。
