According to the present invention, a wider variation of organometallic complexes that can emit phosphorescence can be provided by applying, as a ligand, an organic compound from which a variety of derivatives can be easily synthesized. In particular, an organometallic complex having a sharp emission spectrum is provided. Further, an organometallic complex having high emission efficiency is provided. An organometallic complex represented by the general formula (G1) is provided. In the formula, Ar represents an aryl group, R represents an alkoxy group having 1 to 4 carbon atoms, and R
1
and R
2
individually represent either hydrogen or an alkyl group having 1 to 4 carbon atoms.
根据本发明,通过将一种有机化合物作为配体应用,可以提供更广泛的能够发射磷光的有机金属配合物变体,从该有机化合物可以轻松合成多种衍生物。特别地,提供了一种具有尖锐发射光谱的有机金属配合物。此外,还提供了一种具有高发射效率的有机金属配合物。提供了一种由通式(G1)表示的有机金属配合物。在该式中,Ar代表芳基基团,R代表具有1到4个碳原子的烷氧基团,R1和R2分别表示氢或具有1到4个碳原子的烷基基团。
