Abstract

Two novel ternary europium(III) complexes (Eu-1 and 2) based on modified phenanthroline ring have been successfully synthesized and give characteristic purple-red emissions. The complex with 4-substituted carboxyl group has been proved to act as a selective luminescence quencher for copper(II) ions, as shown by the "on/off" switch phenomenon and the smart responsive changes in the UV-vis region (detection limit up to 0.5 μM). The preliminary data imply that Eu-1 could be applicable as a potential fluorescent sensor for detection of copper(II) ions. © 2010 Elsevier B.V. All rights reserved.
