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, 1 H NMR and 19 F NMR spectroscopy. Selective sensing for Hg 2+ ions through a PET‐based mechanism was evidenced, suggesting application as fluorescent sensor for Hg 2+ of the off‐on type.
