A ratiometric fluorescent chemodosimeter with selective recognition for sulfite in aqueous solution.
A fluorescent chemodosimeter containing a guanidiniocarbonylpyrrole and a 9-(aminomethyl)anthracene moiety has been synthesized. The sensor exhibits ratiometric fluorescence changes for SO(3)(2-) over other anions in 90% water/DMSO. The interesting ratiometric fluorescent changes for SO(3)(2-) are attributed to the fluorescence resonance energy transfer (FRET) and the SO(3)(2-) complex induced photochemical reaction.
