Abstract: We report the synthesis of a novel type of bidentate chiral ligand which structurally derives from the association of a 1,2,3-triazole ring with a chiral oxazoline. Yttrium and lanthanide nitrato-complexes of the new triazolyl–oxazoline ligand were prepared and characterized. The coordination mode of the ligand was ascertained by means of DFT calculations. Trivalent europium and terbium derivatives resulted appreciably photoluminescent upon excitation with UV light, showing the typical ⁵D₀ → ⁷F_J and ⁵D₄ → ⁷F_J emissions, respectively. These species were successfully used for the preparation of luminescent-doped polymeric materials.
