Synthesis of a Flavone Based Fluorescent Probe Bearing a Nitroolefin Moiety for Selective Detection of Cysteine
In this paper, we report the synthesis, characterization and investigation of the optical properties of a new fluorescent probe, 4ʹ-nitroolefinylflavone (4ʹ-NOF) 1, based on a flavone skeleton and bearing a nitroolefin moiety. Upon the addition of cysteine, a remarkable fluorescence enhancement (200 fold) was observed …
