A water stable europium coordination polymer as fluorescent sensor for detecting Fe3+, CrO42-, and Cr2O72- ions

A novel linear chains structure Europium coordination polymer has been synthesized, and it is a promising example of detection for trace amount of Fe3+, CrO42-, and Cr2O72- ions with high selectivity and sensitivity in aqueous solutions, respectively. Furthermore, the luminescent sensing mechanisms of differentiating analytes are explored in detail.368
