Abstract

A light-emitting element including a phosphorescent organometallic complex is provided. The organometallic complex emits phosphorescence in the yellow green to orange wavelength range and has high emission efficiency and high reliability. Thus, the organometallic complex that exhibits phosphorescence is provided. The organometallic complex, in which nitrogen at the 3-position of a pyrimidine ring is coordinated to a 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.

Claims (4)

1. A compound represented by any one of Formulae (100), (101), (110), (112), and (113):

2. A light-emitting device comprising:

a light-emitting layer between a pair of electrodes, the light-emitting layer comprising a compound,

wherein the compound is represented by any one of Formulae (100), (101), (110), (112), and (113):
