  Synthesis, photophysical characterisation and metal ion binding properties of new ligands containing anthracene chromophores

  摘要：

  Two new fluorescent chemosensors for heavy metal ions have been synthesised and their photophysical properties have been investigated. They present a pyridyl-thioether-based binding site and the anthracene moiety as a chromophore. In the experimental conditions used, no evidence is found for the formation of complexes with Pb2+ Zn2+ Cd2+, and Ag+ ions. On the contrary, in acetonitrile solutions both ligands strongly bind Cu2+ and Hg2+ cations according to a 1:1 and a 1:2 (metal:ligand) stoichiometry. In these complexes, the intense luminescence typical of anthracene derivatives is almost completely quenched and this phenomenon can be mainly attributed to an intraligand electron transfer process from the anthracene chromophore to the complexed pyridine. These results are of interest for the development of new chemosensors for the design of efficient electronic tongues for the detection of transition metal ions. (C) 2004 Elsevier B.V.
