A novel organometallic complex with high reliability is provided. The organometallic complex includes iridium and ligands coordinated to the iridium. The ligands are a dipivaloylmethanato ligand and a ligand including a phenyl group to which an alkyl group is bonded and which is bonded to the 5-position of a pyrazine ring.
In the formula, Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms; and R1 and R2 each independently represent a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms. R3 to R6 each independently represent any of hydrogen, halogen, a cyano group, a substituted or unsubstituted amino group, a substituted or unsubstituted hydroxyl group, a substituted or unsubstituted mercapto group, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, and a substituted or unsubstituted heteroaryl group having 3 to 12 carbon atoms.
提供了一种具有高可靠性的新型有机金属配合物。这种有机金属配合物包括铱和配体与铱配位。配体是二戊酰丙酮配体和包括苯基与烷基键合并与吡啶环的5位键合的配体。在公式中,Ar代表具有6到13个碳原子的取代或未取代芳基基团;R1和R2分别独立地代表具有1到6个碳原子的取代或未取代烷基基团。R3到R6分别独立地代表氢、卤素、氰基、取代或未取代氨基、取代或未取代羟基、取代或未取代巯基、具有1到6个碳原子的取代或未取代烷基基团、具有6到13个碳原子的取代或未取代芳基基团以及具有3到12个碳原子的取代或未取代杂环基团中的任意一种。
