Abstract
A new tren-based starburst molecule containing fluorinated 1,2,4-oxadiazoles as fluorophores has been synthesized and its sensing behavior toward several metal cations has been investigated by UV/Vis, fluorescence, 1H NMR and 19F NMR spectroscopy. Selective sensing for Hg2+ ions through a PETbased mechanism was evidenced, suggesting application as fluorescent sensor for Hg2+ of the off-on type.
