A new macrocyclic ligand as a turn-on fluorescent chemosensor for the recognition of Pb 2+ ions

A new asymmetric macrocyclic ligand was synthesized and characterized by NMR studies, X-ray diffraction and mass spectroscopy. Based on the photoinduced electron transfer (PET) fluorescence enhancement mechanism, the ligand has been successfully used for the efficient detection of Pb 2+ in aqueous b...

Summary:A new asymmetric macrocyclic ligand was synthesized and characterized by NMR studies, X-ray diffraction and mass spectroscopy. Based on the photoinduced electron transfer (PET) fluorescence enhancement mechanism, the ligand has been successfully used for the efficient detection of Pb 2+ in aqueous buffer media (pH 7.4). The detection limit of Pb 2+ is up to 9.63 × 10 −10 M.
