title: Solvent effect on the luminescent properties of new europium and terbium nitrate complexes with 3,3,7,7-tetra[N-methyl-N-phenyl(acetamide)-2-oxymethyl]-5-oxanonane.
abstract: The multipodal ligand 3,3,7,7-tetra[N-methyl-N-phenyl(acetamide)-2-oxymethyl]-5-oxanonane (L) and its europium and terbium nitrate complexes were synthesized. The complexes were characterized by elemental analysis, IR, fluorescence spectroscopy and conductivity. The lanthanide atoms are coordinated by O atoms from CO, COC. With the difference of the solvent, the fluorescence properties of solvent effect for the complexes were investigated. Some factors that influencing the fluorescent intensity were discussed.
