A “turn on” fluorescence‐based probe for sensing H 2 S in water via a coordinative‐based approach has been successfully devised. The probe can selectively detect H 2 S in aqueous solutions over other anions, biothiols, and common oxidants such as H 2 O 2 . 1 H NMR spectroscopy and ESI‐MS experiments provide evidence that the turn‐on response in the presence of H 2 S is due to binding of the target anion to the copper center.
