An ICT-based colorimetric and ratiometric fluorescent probe for hydrogen sulfide and its application in live cell imaging†
Abstract
A new naphthalimide-based fluorescent probe for the detection of hydrogen sulfide has been designed and developed. The probe exhibits high selectivity and sensitivity, with efficient colorimetric and ratiometric response for H2S under mild conditions. Furthermore, the probe was successfully used for fluorescence imaging of H2S in living cells.
