Abstract
The synthesis of 1-benzyl-2-((2-Aminoethyl) amino)-5-oxopyrrolidine-3,4-diyl diacetate (boad), an oxopyrrolidine type ligand; designed to coordinate lanthanides (Eu
3+
and Tb
3+
) to get luminescent material. The target complexes showed good photoluminescence properties, which indicate that this type of compound can be used as sensitizers having luminescence for the green (Tb
3+
) and red (Eu
3+
) emission. The obtained results revealed that sensitizer efficiency can be improved by adding ligands like acac (Eu(acac)
3
, which has also enhanced the luminescence quantum output and period for Eu
3+
ions. The ground state geometries were developed by using density functional theory at B3LYP/6-31G** level. The charge transfer analysis and electronic properties were performed. The Europium and Terbium complexes formation with boad ligand was explored based on molecular electrostatic potential, MDC-q charges, and
frontier molecular orbitals
(
FMOs
) analysis.
