Abstract
- A new simple aminohydantoin-based fluorescent chemosensor 1 was designed for sequential detection of Zn 2+ and pyrophosphate in a near-perfect aqueous solution. 1 exhibited significant fluorescence intensity in the presence of Zn 2+ , and the resulting 1 -Zn 2+ complex showed subsequently the fluorescent quenching with pyrophosphate. The detection limit (0.32 μM) of 1 for Zn 2+ was far lower than the guideline of World Health Organization in drinking water. 1 was used to determine Zn 2+ concentration in various water samples. In addition, chemosensor 1 could be applied to sequentially detect Zn 2+ and pyrophosphate in living cells and zebrafish. The sensing mechanism of Zn 2+ by 1 was proposed to be an intramolecular charge transfer with theoretical calculations. [ABSTRACT FROM AUTHOR]
