Three derivatives of phenacyldiphenylphosphine oxide: influence of aromatic and alkyl substituents on the luminescence sensitization of four Ln(NO₃)₃ salts

Abstract

Four β-carbonylphosphine oxide compounds were complexed with four Ln(NO3)3 salts (Ln = Sm, Eu, Tb, Dy). The Ln–ligand complexes were characterized in the solid state (IR, CHN) and as solutions in acetonitrile (NMR, LR-MS, photophysical properties).
