Lipid bilayer interactions of Eu(III) tris-β-diketonato coordination complex

Membrane-associating and bilayer-modifying properties of Eu(III) tris-β-diketonato coordination compound (LC) displaying anti-tumor activity were evaluated using absorption and fluorescence spectroscopy techniques. Quantifying lipid-induced changes in LC absorbance in terms of partitioning formalism yielded partition coefficient of (6.7 ± 1.4) × 103.
