A sulfane sulfur mediated benzodithiolone formation was developed. Based on this reaction, two fluorescent probes (SSP1 and SSP2) for the detection of species (persulfide, polysulfide, elemental sulfur) were prepared evaluated. The showed high selectivity sensitivity to sulfurs. Moreover, SSP2 successfully applied bioimaging sulfurs in living cells.
