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,通过应用一种作为配体的有机化合物,可以提供更广泛的能够发射磷光的有机金属配合物变体,从而可以轻松合成各种衍生物。特别地,提供了具有尖锐发射光谱的有机金属配合物。此外,提供了具有高发射效率的有机金属配合物。提供了由通式(G1)表示的有机金属配合物。在该式中,Ar代表芳基,R代表具有1至4个碳原子的烷氧基,R1和R2分别表示氢或具有1至4个碳原子的烷基。
