摘要：

New ionophores derived front 2,6-bis(N-pyrazolyl)pyridine and aceto/benzophenone have been synthesized and fully characterized. The lanthanide complexes of these new ligands were Studied from their UV-vis and fluorescence data. Eu3+ and Tb3+ complexes were easily formed and their photophysical properties measured. In all cases, lanthanide emission lifetimes were in the range of iris albeit quantum yields were relatively low. Possible flaws in the energy-transfer mechanisms are discussed. (c) 2005 Elsevier Ltd.
