Abstract
- The application of fluorescent method to metal ions detection features high sensitivity, simple operation and real‐time monitoring. A 2,7‐dihydroxynaphthalene‐functionalized dimethyl glycoluril (called clip 1) was synthesized, using a relatively simple method. And it is fully characterized by 1H NMR, 13C NMR, HR‐MS and single crystal X‐ray diffraction. The recognition properties of molecular clip 1 were analyzed systematically toward several metal ions using fluorescence spectroscopy, and it was found that molecular clip 1 is selective and sensitive to Fe3+. At the same time, the clip 1 shows good anti‐interference ability when other metal ions existed. The limit detection of Fe3+ is 3×10−7M. The fluorescence of clip 1 was quenched apparently by Fe3+, which was speculated to be caused by ligand–metal charge transfer mechanism (LMCT). As a new fluorescence probe for Fe3+ ion, it may expanded the application of glycoluril molecular clips. [ABSTRACT FROM AUTHOR]
