What is Highly Selective Colorimetric and Fluorometric Probes for Fluoride Ions Based on Nitrobenzofurazan‐containing Polymers about?

## Abstract We report on a novel colorimetric and fluorometric chemosensor for fluoride ions based on 4‐(2‐acryloyloxyethylamino)‐7‐nitro‐2,1,3‐benzoxadiazole (NBDAE)‐labeled polymers. Upon gradual addition of fluoride ions (F^–^), the green fluorescence emission of NBDAE moieties can be dramatically quenched, accompanied with the distinct colorimetric transition from green to yellow. NBDAE moieties are capable of selectively recognizing F^–^ ions via hydrogen‐bonding (__H__‐bonds) interactions at low F^–^ concentration and subjected to further deprotonation process at high F^–^ concentration. NBDAE‐labeled polymers in organic solvents possess high selectivity and fluorescence “turn‐off” characteristics toward the sensing of F^–^ ions with the detection limit down to ≈0.8 μM. magnified image
