Abstract
The present invention relates to a raw material for a cyclometalated iridium complex, and provides a technique that makes it possible to obtain a cyclometalated iridium complex in higher yield at a lower reaction temperature than using tris(2,4-pentanedionato)iridium(III). The present invention relates to a raw material for a cyclometalated iridium complex, including an organic iridium material for producing a cyclometalated iridium complex, the organic iridium material being a tris(β-diketonato)iridium(III), in which an asymmetric β-diketone is coordinated to iridium.
