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Fe3+和Cu2+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Fe3+和Cu2+。另外,根据Fe3+、Cu2+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。

Abstract: 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 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.
