| 제목 | Fluorescent Chemosensors |
| 초록 | With the aid of supramolecular chemistry, recognizing and sensing anionic or cationic analytes has recently emerged as a key research field. Fluorescence is an important detection method due to its simplicity and high detection limit. Indeed, during recent ten years, there have been a considerable amount of reports regarding ion selective receptors using the fluorescent changes as the means of detection. Various fluorescent chemosensors based on anthracene, Rhodamine B, fluorescein and BODIPY have been studied for the recognition of biologically important analytes. For example, a new water-soluble and fluorescent imidazolium receptor effectively and selectively recognizes the biologically important GTP over other structurally similar anions in aqueous solution of physiological pH 7.4. A new fluorescent sensor based on Rhodamine B (1) displayed an extreme selectivity for Pb2+ over other metal ions examined in acetonitrile. The overall emission change of 100-fold was observed upon the addition of Pb2+ and the selectivity for Pb2+ over Zn2+ was calculated as 200 times. On the other hand, the Zinpyr-1•Zn2+ complex displayed a highly selective and ratiometric fluorescence and UV changes for pyrophosphate compared with H2PO4-. Finally, We report herein utilizing new BODIPY derivatives as “off-on” fluorescent chemosensor and fluorescent chemodosimeter for Cu2+ and Pb2+. |
