Abstract
- A practical hydrazine-carbothioamide-based fluorescent chemosensor TCC (N-(4-chlorophenyl)-2-(thiophene-2-carbonyl)hydrazine-1-carbothioamide) was applied for Zn<superscript>2+</superscript> detection. TCC exhibited selective fluorescence emission for Zn<superscript>2+</superscript> and did not show any interference with other metal ions. In particular, TCC was utilized for the detection of Zn<superscript>2+</superscript> in paper strips, zebrafish and real water samples. TCC could detect Zn<superscript>2+</superscript> down to 0.39 μM in the solution phase and 51.13 μM in zebrafish. The association ratio between TCC and Zn<superscript>2+</superscript> was determined to be 2:1 by ESI-mass and Job plot. The sensing mechanism of TCC for Zn<superscript>2+</superscript> was illustrated to be a chelation-enhanced fluorescence process through spectroscopic experiments and theoretical calculations.
