A fluorescent chemodosimeter containing a guanidinio-carbonylpyrrole and a 9-(aminomethyl)anthracene moiety has been synthesized. The sensor exhibits ratiometric fluorescence changes for SO32- over other anions in 90% water/DMSO. The interesting ratiometric fluorescent changes for SO32- are attributed to the fluorescence resonance energy transfer (FRET) and the SO32- complex induced photochemical reaction.
