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-N3) 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-N3 in the presence of H2S. Density functional theory calculations were performed to validate the mechanism of azide (PN-N3) reduction to amine (PN-NH2) by the strong reducing power of H2S. The potentiality of this chemosensing method is that it could be treated as a simple, less-time-consuming, and cost-effective method for determining H2S in biological samples in the nanomolar range.
