A novel fast-responsive fluorescent probe based on 1,3,5-triazine for endogenous H2S detection with large Stokes shift and its application in cell imaging

A novel fast-responsive fluorescent probe TzAr-H2S based on 1,3,5-triazine was constructed to monitor endogenous H₂S. The probe TzAr-H2S can quickly (only 20 s) detect H₂S with good selectivity, large Stokes shift (100 nm) and low cytotoxicity.
