摘要
目的:研究二茂铁基偶氮苯化合物的光电响应性能及离子识别性能,并研究取代基对其离子识别性能的影响。创新点:考察取代基对于二茂铁基偶氮苯化合物的影响,并提出可能的机理。方法:循环伏安(CV)法和紫外可见吸收光谱(UV-vis)法。结论:通过CV法和UV-vis法研究二茂铁基偶氮苯化合物的离子识别性能,发现硝基取代的化合物对于F^-和H_2PO_4^-具有选择性离子识别作用,而氨基取代的化合物则识别作用不明显。
A series of ferrocene- and azobenzene-based compounds with acyl amine groups attached were designed and synthesized to explore their potential application in anion recognition. Their electro- and photo-properties, and the effect of nitro and amine substituents of the benzene ring on anion recognition were studied by UV-vis absorption spectroscopy （UV） and cyclic voltammetry （CV）. The results showed that a nitro group substituent has a positive effect on the binding affinity and sensitivity, which might be due to the strong hydrogen bonding interaction between the receptor and the guest, while an amino group substituent has a negative effect on the sensitivity. Furthermore, the shift in the UV-vis absorption spectra was observed as a color change, which can be used for the naked-eye detection ofF- and H2PO4 .
