Abstract
Organometal complexes which are obtainable with a good yield by using a ligand which can be easily synthesized are provided. The organometal complexes are excellent in heat resistance. An electroluminescence element having high light emission efficiency is manufactured using the organometal complex. Therefore, the organometal complex represented by the general formula (1) is synthesized. Further, this is applied to the electroluminescence element.
