摘　　要：以9-蒽醛为荧光基团,吡唑和吗啉为识别基团,合成了一种荧光分子探针4-((3-(1-苯基-5-吡啶基-4,5-二氢-1H-吡唑-3-基)蒽-9-基)甲基)吗啉(L)。其结构经1H NMR、13C NMR表征,利用荧光发射光谱和紫外吸收光谱研究其离子识别性能。结果表明,探针L对Fe^3+和Cu^2+具有较强的选择性识别性能,荧光量子产率分别从0.47降到0.21和0.14;探针L的溶液颜色分别从淡黄色变为棕褐色和蓝色,裸眼可判断探针L选择性识别Fe^3+和Cu^2+。另外,根据Fe^3+、Cu^2+和H+不同组合时探针L的量子产率构建了分子水平上的三输入“NOR”逻辑门电路。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 1H NMR and 13C 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 Fe^3+and Cu^2+with the fluorescence quantum yield decreasing from 0.47 to 0.21 and 0.14,respectively.The selective recognition for L to Fe^3+and Cu^2+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 Fe^3+,Cu^2+and H+in different combinations.
