A novel colorimetric chemosensor PBIOSi has been designed and synthesized. The addition of F − to a THF solution of PBIOSi resulted in an obvious color change (from red to green) in a short time because of the specific cleavage of SiO bond in PBIOSi by F − . It was interesting that PBIOSi showed excellent selectivity for F − detection over other halides. The UV‐Vis absorption and fluorescence were changed linearly with the concentration of F − over the range of 0–10 µmol/L.
