A ratiometric fluorescent probe for rapid and sensitive visualization of hypochlorite in living cells†
Abstract
A ratiometric fluorescent probe for ClO− has been developed based on coumarin–hemicyanine, which displayed a colorimetric and fluorescence response to ClO− with high selectivity, fast response (within 2 min) and an extremely low detection limit (0.08 μM). This probe was successfully used to visualize hypochlorite in living cells.
