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 → 7FJ and 5D4 → 7FJ emissions, respectively. These species were successfully used for the preparation of luminescent-doped polymeric materials.
