| Abstract | A ratiometric, near-infrared (NIR), fluorescence and colorimetric probe DNPOCy for hydrogen sulfide (H2S) has been developed. The chemical basis for the operation of the probe is thiolysis of a dinitrophenyl ether, which liberates a cyanine dye chromophore. The probe exhibits a rapid response and high sensitivity to H2S in pure aqueous media, in the near infrared optical window. DNPOCy is highly selective for H2S over other biologically relevant species including biothiols. This probe can be conveniently used for monitoring H2S without the interference from pH dependent effects of physiological media. The practical utility of the probe was demonstrated by its application to the detection of H2S in live cells. |
