摘要

Abstract

A novel conjugated polymer

poly(

)

containing thiourea moieties in main chain is synthesized

via

Suzuki coupling reaction. The addition of cuprous ion quenches the fluorescence of poly(

)

whereas the fluorescence changes slightly upon addition of other metal ions

exhibiting the fluorescent almost turn-off sensing ability towards Cu

. When hydrogen peroxide was added to the solution containing poly(

) and Cu

was oxidized into Cu

resulting in the fluorescence recovery. The H

released from glucose oxidation by glucose oxidase (GOD) also recovered the fluorescence of poly(

)/Cu

solution. The results indicated that the poly(

)/Cu

solution could serve as a sensing platform for hydrogen peroxide and glucose.
