An organometallic iridium complex having high emission efficiency and high heat resistance and emitting yellow light is provided as a novel substance. The organometallic iridium complex includes iridium and a ligand and includes a structure represented by General Formula (G1). The ligand includes a 5H-indeno[1,2-d]pyrimidine skeleton and an aryl group bonded to the 4-position of the 5H-indeno[1,2-d]pyrimidine skeleton. The 3-position of the 5H-indeno[1,2-d]pyrimidine skeleton and the aryl group are bonded to the iridium.
In the formula, Ar represents a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and each of R
1
to R
7
independently represents hydrogen or a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms.
提供了一种具有高发射效率和高耐热性并发出黄光的有机金属铱配合物作为新物质。该有机金属铱配合物包括铱和配体,并包括由通式(G1)表示的结构。配体包括一个5H-吲哚并[1,2-d]嘧啶骨架和与5H-吲哚并[1,2-d]嘧啶骨架的4位键合的芳基基团。5H-吲哚并[1,2-d]嘧啶骨架的3位和芳基基团与铱键合。在公式中,Ar表示具有6到13个碳原子的取代或未取代的芳基基团,每个R1到R7独立地表示氢或具有1到6个碳原子的取代或未取代的烷基基团。
