Abstract

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 Pb²⁺ in aqueous buffer media (pH 7.4). The detection limit of Pb²⁺ is up to 9.63 × 10⁻¹⁰ M.
