Title:
METHOD FOR PRODUCING COMPLEX OF TRISORTHO-METALATED IRIDIUM, LIGHT-EMITTING MATERIAL USING SAID COMPLEX, AND LIGHT-EMITTING ELEMENT
Document Type and Number:
WIPO Patent Application WO/2012/057138
Kind Code:
A1
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 for a material for an organic electroluminescence element. The method for producing a complex of trisortho-metalated iridium of the present invention involves the following steps in said order: a step (1) for preliminarily heating a complex of ortho-metalated iridium and/or a bidentate organic ligand; a step (2) for combining the complex of ortho-metalated iridium and the bidentate organic ligand; and a step (3) for reacting the complex of ortho-metalated iridium with the bidentate organic ligand.
