Substituted pyrimidinato iridium complexes and substituted pyrazinato iridium complexes having an alicyclic diketone ligand |
摘要 |
As a novel substance having a novel skeleton, a novel organometallic complex that can emit phosphorescence in the green to red wavelength region and has high emission efficiency and a high yield of synthesis is provided. One embodiment of the present invention is an organometallic complex in which a diketone having a five-membered or six-membered alicyclic structure composed of carbon and hydrogen is a ligand.;
In the formula, L represents a bidentate aromatic ligand and has at least a bond between carbon of an aromatic ring in the aromatic ligand and Ir. X represents a five-membered or six-membered alicycle composed of carbon and hydrogen. Further, R1 represents a substituted or unsubstituted alkyl group having 1 to 4 carbon atoms. |
