Terminal group effects on the fluorescence spectra of Eu(III) nitrate complexes with a family of amide-based 1,10-phenanthroline derivatives
摘要:
Four ligands 1,10-phenanthroline-5,6-bis(N,N-dibenzyl-l'-oxopropylamide) (L-a) 1,10-phenanthroline-5,6-bis(N-methyl-N-benzyl-l'oxopropylamide) (L-b) 1,10-phenanthroline-5,6-bis(N-benzyl-l'-oxopropylamide) (L-c) and 1,10-phenanthroline-5,6-bis(N,N-diethyl-l'oxopropylamide) (L-d), and their lanthanide(III) (La and Eu) complexes were synthesized. The complexes were characterized by elemental analysis, IR, fluorescence spectroscopy and conductivity. The lanthanide atoms are coordinated by O atoms from C=O, Ar-O-C and N atoms from phen With the difference of the ligands, the fluorescent intensities of the Eu(Ill) complexes vary regularly in the THF solution. Some factors that influence the fluorescent intensity were discussed. (c) 2005 Elsevier B.V. All rights reserved.
amide-based 1,10-phenanthroline (phen) derivative and its complexes with europium(III) and terbium(III) ions were synthesized. The complexes were characterized by elemental analysis, infraredspectra and conductivity. The europium and terbium ions were coordinated by O atoms of C=O, Ar-O-C and N atoms of phen. The fluorescence properties of the complexes in THF, dioxane, MeCN and DMF were investigated. Under
