“…[5][6][7][8] These applications of lanthanide complexes are based on their unique luminescence characteristics such as large Stokes displacement, narrow and sharp emission peaks, and high quantum efficiency. [9][10][11] However, these transitions are prohibited by the parity selection rule. Therefore, weak absorption results due to the low value of the molar extinction coefficient of Ln ions.…”

A series of lanthanide (samarium and terbium) β‐diketonates with heteroaromatic auxiliary ligands was synthesized. The prepared complexes were characterized through electrochemical, thermal, and spectroscopic analyses. Infrared analysis revealed the binding of the respective metal ion to oxygen and nitrogen atoms of diketone and ancillary ligands. Thermogravimetry/differential thermogravimetry profiles provided thermal information and specified the high thermal stability of the prepared complexes. The complexes exhibited the sharp and structured Ln‐based emission in the visible region upon irradiation in the ultraviolet range. Photophysical analysis demonstrated the green and orange‐red emission due to the respective characteristic transitions of Tb3+ and Sm3+ ions. Photophysical properties affirmed the luminous behaviour of the synthesized complexes. These luminous lanthanide complexes could be used as emitting materials in the design of organic light‐emitting diodes.

“…[12], 2,2 -bipyridine-6,6 -dicarboxylate ligand in complexes is a highly efficient sensitizer for the "antenna effect". Thus, the use of 2,2 -bipyridine-6,6 -dicarboxylate ligands, especially amides-N 6 ,N 6 -diisopropyl-[2,2 -bipyridine]-6,6dicarboxamide (BDCA), in europium and terbium complexes, can lead to a relatively higher QY compared to several europium and terbium complexes with some ligands, including phenanthroline derivatives, thenoyltrifluoroacetone, β-diketonates, substituted pyridine, and 2,2 -bipyridine derivatives [13][14][15][16][17][18][19].…”

Photoluminescent lanthanide complexes of Eu3+ and Tb3+ as central atoms and N6,N6’-diisopropyl-[2,2′-bipyridine]-6,6′-dicarboxamide as ligand were synthesized. The structure of these complexes was established by single-crystal X-ray diffraction, mass spectrometry, 1H and 13C nuclear magnetic resonance, ultraviolet-visible, infrared spectroscopy, and thermogravimetry. Bipyridinic ligands provide formation of coordinatively saturated complexes of lanthanide ions and strong photoluminescence (PL). The Eu3+- and Tb3+-complexes exhibit PL emission in the red and green regions observed at a 340 nm excitation. The quantum yield for the complexes was revealed to be 36.5 and 12.6% for Tb3+- and Eu3+-complexes, respectively. These lanthanide compounds could be employed as photoluminescent solid-state compounds and as emitting fillers in polymer (for example, polyethylene glycol) photoluminescent materials.
