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
合成了一种含有氟化 1,2,4-恶二唑作为荧光团的基于 tren 的新星爆分子,并通过 UV/Vis、荧光、 1 H NMR 和 19 F NMR 光谱研究了其对几种金属阳离子的传感行为。证明了通过基于 PET 的机制对 Hg 2+ 离子的选择性传感,这表明其可用作关断型 Hg 2+ 的荧光传感器。
