Synthesis, Characterization, and Photoluminescence of a Novel Eu-Containing Polymer Precursor: {Tris(acetylacetonate)5-acrylamido-1,10-phenanthroline}Europium(III)

Abstract:

A new europium complex, Eu (acac)₃Aphen (where Hacac and Aphen stand for acetylacetone and 5-acrylamido-1,10-phenanthroline, respectively), was synthesized and characterized by elemental analysis, IR, UV and photoluminescence (PL) spectra. The ligand Aphen not only serves as an antenna ligand but also offers a functional group for polymer precursor. The room-temperature PL spectra of the europium (III) complex are composed of the typical Eu³⁺ red emission, assigned to transitions between the first excited state (⁵D₀) and the multiplet (⁷F₀₄). Compared to Eu (acac)₂AA (where HAA is acrylic acid), Eu (acac)₃Aphen exhibits greatly enhanced quantum efficiency (i.e., 14.1% vs 28.5%) and longer ⁵D₀ lifetime (260 μs vs 568 μs).
