A Copper Porphyrin for Sensing H2S in Aqueous Solution via a "Coordinative‐Based" Approach. Issue 13 (7th April 2015) - Mirra, Silvia
Abstract: A "turn on" fluorescence‐based probe for sensing H2 S in water via a coordinative‐based approach has been successfully devised. The probe can selectively detect H2 S in aqueous solutions over other anions, biothiols, and common oxidants such as H2 O2 . 1 H NMR spectroscopy and ESI‐MS experiments provide evidence that the turn‐on response in the presence of H2 S is due to binding of the target anion to the copper center. Abstract : We devised a new, fast, simple, and cost‐effective probe for monitoring hydrogen sulfide. Proof‐of‐principle results that a copper porphyrin complex can be successfully implemented as a turn‐on sensing system for H2 S via a coordinative‐based approach are reported.
