A "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.

Abstract
A "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.File in questo prodotto:
