Synthesis, characterization and luminescent properties of lanthanide complexes with an unsymmetrical tripodal ligand

摘要

Solid complexes of lanthanide nitrates with a new unsymmetrical tripodal ligand, bis(2'-benzylaminoformyl)phenoxyl)ethyl(ethyl)amine (L) have been synthesized and characterized by elemental analysis, infrared spectra and molar conductivity measurements. At the same time. the luminescent properties of the Sm(III), Eu(III), Tb(III) and Dy(III) nitrate complexes in solid state were also investigated. Under the excitation of UV light, these complexes exhibited characteristic emission of central metal ions. (c) 2008 Elsevier B.V. All rights reserved.
