The anionic fluorescent dye, aminopyrene trisulfonic acid (APTS), was synthesized and used in a solution-based two-component glucose-sensing system comprising the dye and a boronic acid-appended viologen. The fluorescence of the dye was quenched in the presence of the viologen and the fluorescence restored upon glucose addition. An important feature of this fluorophore is that it can be covalently bonded to a polymer through the ...
