- •
DB1 and DB2 show rapid response, high selectivity and sensitivity for bisulfite/sulfite anions with significant ratiometric fluorescent signal changes.
- •
The detection limit was determined to be 0.16 μM for DB1 and 0.57 μM for DB2, respectively, which is sufficient to probe the HSO3− concentration in cells.
- •
DB1 and DB2 were successfully applied for bioimaging SO2 derivatives in living cells under one- and two-photon confocal microscopy.
