Abstract: An oil soluble flavone derivative (FL-C) with lariat ether was able to coordinate with β-CDin aqueous solution to form 1:1 host-guest complex. Because it was still located at the outside of β-CD, the lariat ether keeps the complexation ability with alkali and a alkaline-earth cation, leading to the fluorescence intensity change of this compound. The results indicated that the using of oil-soluble probe in β-CDaqueous solution for the detection of alkali and alkaline earth cations was successful.

Key words: Flavone derivative, Lariat ether, Host-guest complex, Fluorescence probe
