Abstract
A new fluorogenic calix[4]arene containing one pendent N-dansylcarboxamide group has been synthesized. The ligand demonstrates selective optical recognition of Tl+ and Hg2+ in solvent extraction from aqueous solutions with high content of Na+. Complexation of Tl+ and Hg2+ produces contrasting changes in the fluorescence spectrum of this sensor. Partial cone is the dominant calixarene conformation in the complex with Tl+.
