摘要
A novel benzothiazole derivative J as a fluorescent chemosensor for Zn2+ has been designed and synthesized. The chemosensor J exhibits high selectivity and sensitivity to Zn2+ as fluorescence turn-on behavior, which the other cations do not make sense. The detection limit calculated by fluorescence titration method was 1.64 x 10(-8) M. Furthermore, the generated J-Zn2+ ensemble could recover the enhanced fluorescence upon the addition of EDTA generating an on-off-on recycle. In addition, the test strip based on J was fabricated, which could act as a convenient and efficient Zn2+ test kit. [GRAPHICS] .
