摘要：
A fluorescent probe L was synthesized using 9-anthracene aldehyde as fluorescent group with pyrazoline and morpholine as recognition group, and its structure was characterized by H-1 NMR and C-13 NMR. The ion recognition performance of probe L was investigated by fluorescence emission spectra and ultraviolet absorption spectra. The results show that L has strong selective recognition performance for Fe3+ and Cu2+ with the fluorescence quantum yield decreasing from 0.47 to 0.21 and 0.14, respectively. The selective recognition for L to Fe3+ and Cu2+ was distinguished by naked eye along with color change from pale yellow to brown and blue, respectively. In addition, a three-input" NOR" logic gate circuit was constructed at the molecular level by the quantum yield of L for Fe3+, Cu2+ and H+ in different combinations.y
