摘　　要：A simple carbazole hydrozone derivative（l） was synthesized and used as an optical probe for fluoride recognition in CH3CN. Receptor I exhibited colorimetric and fluorescent dual-channel response to fluoride anions. Addition of fluoride to a receptor 1 solution in CH3CN induced a distinct color change from yellow to magenta, the solution also displayed significant fluorescence blue shift. Thus receptor 1 exhibited dual-channel responses to fluo- ride with a hi~.h selectivitv and senitivltvA simple carbazole hydrozone derivative（l） was synthesized and used as an optical probe for fluoride recognition in CH3CN.
