Title:
IRIDIUM COMPLEX PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/043016
Kind Code:
A1
Abstract:
This iridium complex production method for producing tris(β-diketonato) iridium by reacting β-diketone with an iridium compound, is characterized by subjecting the iridium compound to activation treatment involving (a) alkali treatment: treatment for adding an alkali to a solution of the iridium compound and making the pH of the solution more alkaline than before addition of the alkali, and greater than or equal to pH 10, and (b) acid treatment: treatment for adding an acid to the solution that has undergone the aforementioned alkali treatment and which, while making the pH of the solution more acidic than before the addition of the acid, results in a 0.1-10 pH difference in the solution before and after addition of the acid; after activation of the iridium compound, said iridium compound is reacted with the β-diketones. Thus, it becomes possible to produce tris(β-diketonato) iridium using a wide range of β-diketones.
