We demonstrate that the copolymers containing boronic acid and pyrene units can be utilized for the fluorometric sensing of hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>) in aqueous solutions. The copolymer exists in a relatively extended conformation in the absence of H<sub>2</sub>O<sub>2</sub>, whereas the polymer chain is contracted by the reaction of boronic acid moieties with H<sub>2</sub>O<sub>2</sub> to form phenol groups. This conformational change induces aggregation of the originally i ...[more]
