Title:
トリスオルトメタル化イリジウム錯体の製造方法及びそれを用いた発光材料並びに発光素子
Document Type and Number:
Japanese Patent JP5881216
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a novel production method for obtaining, at a high selectivity compared to the conventional production method in which a reaction substrate is heated and is subjected to a reaction after being mixed, a complex of trisortho-metalated iridium, in particular, a complex of a facial trisortho-metalated iridium suitably used as a material for an organic electroluminescence element. The method for producing a complex of trisortho-metalated iridium of the present invention is a method for producing a complex of trisortho-metalated iridium represented by chemical formula (6) by reacting, as the reaction substrate, a complex of ortho-metalated iridium represented by chemical formula (4) with a bidentate organic ligand represented by chemical formula (5), the method involving the following steps in said order: a step (1) for preliminarily heating a reaction solvent; a step (2) for adding the complex of ortho-metalated iridium and the bidentate organic ligand to the preliminarily-heated reaction solvent; and a step (3) for reacting the complex of ortho-metalated iridium with the bidentate organic ligand.
