In this paper, we successfully synthesized a simple and versatile fluorescent probe. This probe was not only easily prepared with a high yield, but also showed rapid selective and sensitive responses for Cys/Hcy and GSH. The probe can be used as a naked-eye detector for Cys/Hcy and GSH from other analytes. As a fluorescent sensor, it can be used to simultaneously detect and discriminate Cys/Hcy from GSH with two fluorescent emission signals without spectral crosstalk.
