Document Type and Number:
Japanese Patent JP6598906
Kind Code:
B2
Abstract:
Provided is a light-emitting element including a phosphorescent iridium metal complex that emits phosphorescence in a yellow green to orange wavelength range, and has high emission efficiency and reliability. Thus, further provided is the phosphorescent iridium metal complex that emits phosphorescence in the yellow green to orange wavelength range. Further provided are a light-emitting device, an electronic appliance, and a lighting device each of which includes the above light-emitting element. The light-emitting element includes an EL layer between a pair of electrodes, and the EL layer contains a phosphorescent iridium metal complex where nitrogen at the 3-position of a pyrimidine ring having an aryl group bonded to the 4-position is coordinated to a metal, a substituent having a carbazole skeleton is bonded to the 6-position of the pyrimidine ring, and the aryl group bonded to the 4-position of the pyrimidine ring is ortho-metalated by being bonded to the metal.
