3.1 Optimized geometries of the ground
state
Eu(III) complexes with β-diketones were chosen among other Ln(III)
coordination compounds for their intensive emission properties due to
the high molar absorption coefficients of ligands and suitable positions
of the excited levels of Eu(III) and ligands.[1-6]Ligand environment of Ln(III) complexes specifies their LC behavior and
emission properties. In this work we selected objects with various
substituted β-diketones and Lewis bases - Bpy17-17(5,5’diheptadecyl-2,2’-bipyridine) and Phen (1,10phenanthroline), see
Figure 1.
