摘　　要：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 Si-O 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 ofF over the range of 0- 10 μmol/L.A novel colorimetric chemosensor PBIOSi has been designed and synthesized.
