Ion-Induced FRET On−Off in Fluorescent Calix[4]arene

A novel calix[4]arene bearing one 2,3-naphthocrown-6 and two coumarin amide units at the lower rim in partial-cone conformation (1) was synthesized as a colorimetric and FRET-based fluorometric sensor for F- and Cs+ ions. Intramolecular FRET from the naphthalene emission to the coumarin absorption a...

Description
Summary:A novel calix[4]arene bearing one 2,3-naphthocrown-6 and two coumarin amide units at the lower rim in partial-cone conformation (1) was synthesized as a colorimetric and FRET-based fluorometric sensor for F- and Cs+ ions. Intramolecular FRET from the naphthalene emission to the coumarin absorption affords high fluorescence selectivity toward F- and Cs+ ions.
