Abstract :
Lanthanide complexes with ortho-phosphorylated phenolate ligands LnL3 (Ln = Eu, Tb, Lu; HL1 = 2-di(p-tolyl)phosphorylphenol; HL2 = 2-diphenylphosphoryl-4-ethylphenol) were synthesized for the first time and characterized by elemental analysis, FTIR, 1H, 31P NMR spectroscopy, LDI-TOF mass-spectrometry. The energy gap between the triplet energy level and the corresponding resonance level of a lanthanide ion (5D1 for Eu3+ and 5D4 for Tb3+) is optimal for luminescence sensitization of only terbium ions. Bright green photo- and electroluminescence of terbium complexes was demonstrated.
