Abstract
Based on ‘1,2,4-triazine’ methodology, a new lanthanide( iii ) ligand, 5-(4-dodecyloxyphenyl)-2,2 ’ -bipyridine-6 ’ -carboxylic acid, was synthesized, and its luminescent europium( iii ) complex was prepared. The solubility in organic solvents for both the ligand and its europium complex was provided by the presence of a long aliphatic dodecyl moiety. The photophysical properties of the europium( iii ) complex were examined, the fluorescence quantum yield and the europium cation luminescence quantium yield were determined.
