  • A Rhodamine-Based Off–On Fluorescent Chemosensor for Selectively Sensing Cu(II) in Aqueous Solution
    作者:Ruiren Tang、Kang Lei、Ke Chen、Hua Zhao、Jingwen Chen
    DOI:10.1007/s10895-010-0698-x
    日期:2011.1
    A novel chromogenic and fluorogenic chemosensor RhB-pMOSal comprising a rhodamine fluorophore and a salicylaldehyde receptor being connected by an iminohydrazine link was synthesized and fully characterized. Its sensing behavior toward various metal ions in neutral aqueous solution was investigated by absorption and fluorescence spectroscopy. RhB-pMOSal exhibited a reversible and sensitive “turn-on” response of absorption and fluorescence toward Cu2+ in aqueous acetonitrile solution. Approximate 65 and 6-fold enhancement in the absorbance at 556 nm and fluorescence intensity at 573 nm were estimated when equivalent Cu2+ was added to the RhB-pMOSal solution. Under the same conditions, RhB-pMOSal displayed more sensitive than a reported analogue RhB-Sal to Cu2+ ion. The competition experiments for Cu2+ mixed with common metal ions exhibited no obvious change in absorption and emission except Cr3+ ion that can induce the fluorescence quenching of RhB-pMOSal to some extent.
    合成了一种新型的显色和荧光化学传感器RhB-pMOSal,该传感器由罗丹明荧光团和香草醛受体通过亚氨基肼链接连而成,并进行了全面表征。通过吸收光谱和荧光光谱研究了其在中性水溶液中对各种金属离子的感应行为。RhB-pMOSal在水相乙腈溶液中对Cu²⁺表现出可逆且灵敏的“打开”吸收和荧光响应。当向RhB-pMOSal溶液中添加等量的Cu²⁺时,在556 nm处的吸收和在573 nm处的荧光强度分别增加了约65倍和6倍。在相同条件下,RhB-pMOSal对Cu²⁺离子的灵敏度优于已报道的类似物RhB-Sal。对Cu²⁺与常见金属离子的竞争实验显示,在吸收和发射中没有明显变化,除了Cr³⁺离子可能在一定程度上引起RhB-pMOSal的荧光淬灭。

    A new rhodamine-based fluorescent probe RSP was facilely synthesized. Interestingly, the RSP-Hg-ClO4 ensemble can serve as a selective fluorescent probe for iodide and bromide based on metal ion removal and anion ligand exchanging, which is a novel rhodamine-based fluorescence sensing mechanism. Moreover, RSP can recognise Hg2+ selectively in 99% aqueous solution.
