英文摘要: New colorimetric and fluorometric fluoride ion probe, anthra[1,9- cd ]pyrazol- 6(2 H )-one ( 1 ), was synthesized by one-step condensation. The probe 1 shows F-selective color change from colorless to pink and appearance of red fluorescence. The fluorescence quantum yield of free probe 1 in DMSO was calculated to be 0.03. After addition of 15 equiv. of F, its fluorescence quantum yield can be increased to 0.37. The analytical detection limit for F was 2.8 × 10− 7 M. 1H NMR analysis and DFT calculation show that the F-induced colorimetric and fluorometric responses of 1 are driven by deprotonation process.
