A unique method has been developed for comparative analysis of H 2 S produced from food samples from our daily diet, both qualitatively and quantitatively. The selective detection of H 2 S 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 H 2 S. 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 H 2 S. The potentiality of this chemosensing method is that it could be treated as a simple, less-time-consuming, and cost-effective method for determining H 2 S in biological samples in the nanomolar range.
