摘要：

New fluorogenic ionophores based upon the p-tert-butylcalix[4]arene-azacrown ethers having anthrylmethyl moieties as the fluorophore have been prepared and their fluoroionophoric properties were investigated. Diazacrown-based derivative 5 exhibited a relatively well-optimized sensing behaviour towards Hg2+ ions compared with the triazacrown analogue 6. A fluorescence enhancement of about 87-fold was observed for the 5-Hg2+ system in a MeOH-THF mixed solvent system.
