Title:
ORGANOMETALLIC COMPLEX
Document Type and Number:
Japanese Patent JP2009161563
Kind Code:
A
Abstract:

To obtain a phosphorescent organometallic complex to be used for a light-emitting element, a light-emitting element that uses the phosphorescent organometallic complex and has a high luminous efficiency, and a light-emitting device that uses the light-emitting element and has low power consumption.

The organometallic complex has a structure represented by general formula (1). In the formula, R1 is an alkyl group. R2 and R3 represent each any one of hydrogen, a halogen atom, an acyl group, an alkyl group, an alkoxy group, an aryl group, a cyano group, and a heterocyclic residue. Ar is one of an aryl group having an electron-withdrawing substituent group and a heterocyclic residue having an electron-withdrawing substituent group, and M is one of the elements of groups 9 and 10.
