Abstract
A dipyridyltriphenylamine derivative, (E)-4-(2-nitrovinyl)-N,N-bis(4-(pyridin-4-yl)-phenyl)aniline, was synthesized as a fluorescent probe for sulfite ion, which can be used in detecting excessive addition of sulfite in the food industry. The chemodosimeter can output far-red to near-infrared emission under both aqueous and solid state conditions exhibiting potential applications in the field of luminescent functional materials. Based on synchronous fluorescence spectroscopy, a ratiometric method was developed for determination of sulfite ion with small overlap in the emission spectrum, whose emission band is narrower than that observed in normal emission spectrum.
