Chemical sensors that detect specific chemicals have been widely applied in environmental sensing, industrial goods, food processing, and bio-technology. Chemical sensors include ion sensors, gas sensors, humidity sensors. As the smallest ions, fluoride ions play a very important role in chemical and biological processes. It is a challenge to study chemical sensors that recognize the small amounts of fluoride ions. Herein, we synthesized conjugated azonaphthol-based polymers by Suzuki coupling reaction. Upon exposure on fluoride ion, hydroxyl groups in the azonaphthol molecules were deprotonated. We confirmed detection of fluoride ion by fluorescence quenching as well as ratiometric color change of conjugated azonaphthol-based polymers. In addition, the conjugated azonaphthol-based polymer has advantages, which is good sensitivity, high selectivity, naked-eyes detection. Therefore, synthesized conjugated azonaphthol-based polymer is a potential candidate as a chemosensor. |
