- •
The proposed recognition mechanism is based on a Michael-type addition reaction toward the probes, induced by SO2-derivatives.
- •
The studied Michael-type addition reactions are favored by micellar-media.
- •
The probes showed excellent selectivity for bisulfite over various other typical interferences species including biothiols.
- •
The probes can be applied to the quantitative and qualitative determination of bisulfite in real samples with high precision.
- •
Probe 1 was cell-permeable and it can be used to monitor bisulfite levels in living cells.
