Abstract
AbstractA “turn on” fluorescence‐based probe for sensing H2S in water via a coordinative‐based approach has been successfully devised. The probe can selectively detect H2S in aqueous solutions over other anions, biothiols, and common oxidants such as H2O2. 1H NMR spectroscopy and ESI‐MS experiments provide evidence that the turn‐on response in the presence of H2S is due to binding of the target anion to the copper center.
