摘　　要：A series of fluorinated pyrazoline derivatives were synthesized by the reaction of fluorinated chalcone with hy- drazine ArNHNH2 （Ar=4-BrC6F4, 4-CIC6H4, C6Hs, 4-CH3C6H4 and 4-CH3OC6H4）, The structures of all these compounds were fully supported by their spectroscopic data and one of products was further confirmed by X-ray single crystal diffraction analysis. The capability of fluorinated triaryl-2-pyrazolines to detect metal cations was in- vestigated, by monitoring changes in their fluorescence spectra in the presence of Cd^2＋, Co^2＋, Cu^2＋, Mn^2＋, Ni^2＋ and Zn^2＋.A series of fluorinated pyrazoline derivatives were synthesized by the reaction of fluorinated chalcone with hy- drazine ArNHNH2 （Ar=4-BrC6F4, 4-CIC6H4, C6Hs, 4-CH3C6H4 and 4-CH3OC6H4）, The structures of all these compounds were fully supported by their spectroscopic data and one of products was further confirmed by X-ray single crystal diffraction analysis.
