摘要: 连有套索冠醚的油溶性探针化合物(FL-C)在水溶液中能与β-CD相络合形成1:1主-客体配合物.由于套索冠醚仍处于β-CD的外侧,因此它具有能络合水溶液中碱金属和碱土金属的能力,导致探针分子荧光强度的变化.结果表明,本方法可成功地使油溶性探针化合物在水相中得到应用.

关键词: 黄酮衍生物, 套索冠醚, 主-客体络合物, 荧光探针

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
