Saccharide Detection Based on the Amplified Fluorescence Quenching of a Water-Soluble Poly(phenylene ethynylene) by a Boronic Acid Functionalized Benzyl Viologen Derivative
The amplified quenching of an anionic conjugated polymer, sulfonated poly(phenylene ethynylene) (PPE-SO3 -), by a cationic quencher comprising a boronic acid functionalized benzyl viologen (p-BV2+), has been used to optically detect sugars. In the absence of sugar, a strong polymer/quencher interact...
