ORGANOMETALLIC COMPLEX, LIGHT EMITTING ELEMENT, LIGHT EMITTING DEVICE, ELECTRONIC APPLIANCE, AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light emitting element including a phosphorescent organometallic complex, the organometallic complex emitting phosphorescence in the yellow green to orange wavelength range and having high emission efficiency and high reliability, and thus to provide the organometallic complex that exhibits phosphorescence.SOLUTION: An organometallic complex in which nitrogen at the 3-position of a pyrimidine ring is coordinated to metal, a carbazole skeleton is bonded to the 4-position of the pyrimidine ring, and the carbazole skeleton is bonded to the metal, is used as an emission center. The metal is preferably a Group 9 element or a Group 10 element, more preferably iridium.
