| 摘 要： | 设计合成了含有香豆酰肼官能团的铜离子荧光探针,N,N-二乙基氨基香豆素-3-酰肼吡啶醛(XB),该探针在水溶液中V(CH3CN):V(H2O)=1:1]对铜离子识别和检测具有较高的灵敏度和选择性。碱金属和碱土金属离子K+、Na+、Mg2+、Ca2+以及过渡金属离子Cr3+、Mn2+、Fe3+、Co2+、Ni2+、Zn2+、Cd2+、Hg2+和Ag+等对Cu2+离子的识别无显著影响。光谱滴定和ESI-MS谱表明Cu2+离子与XB以1:2的化学计量比形成配合物。

| Abstract: | By combining 7-diethylamino-2-oxo-2H-chromene-3-carbohydrazide with 2-pyridylaldehyde into one molecule,fluorescent probe XB was synthesized for detection of Cu2+ in aqueous solution V(CH3CN) ∶ V(H2O)=1 ∶ 1). The probe is highly selective for Cu2+ over biologically relevant alkali metals, alkaline earth metals and the first row transition metals such as Cr3+,Mn2+,Fe3+,Co2+,Ni2+,Zn2+,Cd2+ and Hg2+. Spectrophotometric titration and ESI-MS spectra indicate the formation of a 1 ∶ 2 complex of Cu2+ with XB. |
