An indole-based fluorescent chemosensor was synthesized to detect Zn. displayed a marked fluorescence increment with Zn. The detection limit (0.41 μM) of for Zn was greatly below that suggested by the World Health Organization. can quantify Zn in real water samples. More significantly, could determine and depict the presence of Zn in zebrafish. The detecting mechanism of toward Zn was illustrated by fluorescence and UV-visible spectroscopy, DFT calculations, H NMR titration and ESI mass.
