Consumption of H₂S from Our Daily Diet: Determination by a Simple Chemosensing Method.

ABSTRACT: A unique method has been developed for comparative analysis of H₂S produced from food samples from our daily diet, both qualitatively and quantitatively. The selective detection of H₂S has been executed by introducing a simple chemodosimeter (PN-N ₃ ) that gives response on the basis of intramolecular charge transfer. UV-vis, fluorimetric, and NMR titrations were performed to demonstrate the sensing mechanism and electronic environment of PN-N ₃ in the presence of H₂S. Density functional theory calculations were performed to validate the mechanism of azide (PN-N ₃ ) reduction to amine (PN-NH ₂ ) by the strong reducing power of H₂S. The potentiality
