TL;DR: In this paper, the authors investigated new Eu(III) complexes coordinated by both of nitrogen and oxygen by using 2-(5-isoxazolyl)phenol ligand in the same condition as corresponding 2,2-dipyridylamine reaction.
Abstract: Europium complexes exhibits sharp red emission bands due to its 4f electrons. Especially those coordinated by chelating oxygen ligands such as β-diketones show good stability in the air and can be used as red emitting materials. To improve the emitting color or luminescence efficiency, neutral nitrogen donating ligand such as phenanthroline or 2,2'-bipyridine was added to the Eu compound coordinated by oxygen donating ligands. However, Eu compounds only with nitrogen donating ligands especially with aromatic nitrogens are not much compared to the oxygen ligated Eu compounds due to weaker metal-nitrogen interaction. We had reported that Eu(III) complex obtained from the reaction of EuCl3 and 2,2'-dipyridylamine was decomposed to 2,2'dipyridinium chloride and Eu compound in methanol solution. Herein, we investigate new Eu(III) complexes coordinated by both of nitrogen and oxygen by using 2-(5-isoxazolyl)phenol ligand in the same condition as corresponding 2,2'dipyridylamine reaction.
