Abstract
AbstractNew lanthanide‐based luminescent coordination compounds containing quinoline derivatives and 2‐(4‐hydroxyazobenzene)benzoic acid (HABA) were synthesized. Fourier transform infrared spectroscopy (FTIR), UV‐Vis spectra, Elemental analyses, Energy dispersive X‐ray fluorescence (EDXRF), and mass spectrometry (MALDI) were applied for six complexes′ structural elucidation. In addition, photoluminescence spectroscopy was performed in the solid state. Eu3+ and Tb3+ compounds linked to the π‐conjugated system described energy transfer to the metal through the antenna effect. Emission spectra depicted bands at 616–617 nm, characteristics of red light for Europium complexes, assigned as hypersensitive 5D0→7F2 transition, and depicted bands at 540–542 nm (green light) for Terbium complexes, assigned as 5D4→7F5 transition.
