A novel 2D lanthanide coordination polymer {Eu-CP (1)} based on a 3-bis(3-carboxyphenyl)imidazolium (L) ligand was successfully assembled through a solvothermal method. Luminescence tests indicate that 1 has excellent selectivity and sensitivity to detect Fe3+/Fe2+, Cr2O72-, and a series of nitroaromatic explosives. Interestingly, 1 can effectively distinguish CrVI anions (CrO42-/Cr2O72-), which is difficult for most of the reported CPs. Furthermore, in the detection process, 1 can be simply and quickly regenerated and reused at least five times. As far as we know, 1 is the first multifunctional Eu-CP used as a luminescent probe to detect Fe3+/Fe2+, Cr2O72-, and a series of nitroaromatic explosives (NAEs) based on the imidazolium derivative.
一种基于 3-双(3-羧基苯基)咪唑啉（L）配体的新型二维镧系配合物{Eu-CP(1)}通过溶剂热法成功组装。发光测试表明，1 对 Fe3+/Fe2+、Cr2O72-和一系列硝基芳烃炸药具有优异的选择性和灵敏度。有趣的是，1 可以有效区分 CrVI 阴离子（CrO42-/Cr2O72-），这对于大多数报道的 CPs 来说是很难的。此外，在检测过程中，1 可以简单快速地再生和重复使用至少五次。据我们所知，1 是第一个基于咪唑啉衍生物的多功能 Eu-CP，可用作发光探针来检测 Fe3+/Fe2+、Cr2O72-和一系列硝基芳烃炸药（NAEs）。
