文摘
- •
A Schiff-base fluorescent and colorimetric probe CS was synthesized.
- •
CS is a naked-eye chemosensor for Cu2+ and a fluorescent chemodosimeter for Hg2+.
- •
The mercury-promoted hydrolysis of CS on the imine C
N bond was responsible for Hg-induced fluorescence enhancement.- •
The coordination of Cu2+ to CS induced the fluorescence quenching and a pale yellow solution was developed.
- •
Time-dependent fluorescence images were carried out in living cell.
