摘要 |
As a novel substance having a novel skeleton, an organometallic complex with high emission efficiency which achieves improved color purity by a reduction of half width of an emission spectrum is provided. One embodiment of the present invention is an organometallic complex in which a β-diketone and a six-membered heteroaromatic ring including two or more nitrogen atoms inclusive of a nitrogen atom that is a coordinating atom are ligands. In General Formula (G1), X represents a substituted or unsubstituted six-membered heteroaromatic ring including two or more nitrogen atoms inclusive of a nitrogen atom that is a coordinating atom. Further, R1 to R4 each represent a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.; |

1. An organometallic complex represented by formula (G1): wherein: X represents any of formulae (X1) to (X3): R1 to R4 each represent a substituted or unsubstituted alkyl group having 1 to 6 carbons; and R5 to R13 each represent any of hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbons, and a substituted or unsubstituted phenyl group. |
