    摘要: Disclosed is a phosphorescent organometallic complex having: a 6-membered aromatic heterocycle having a nitrogen atom; iridium or platinum to which the nitrogen atom coordinates; and an aryl group which is bonded to an α-carbon of the nitrogen atom and is ortho-metalated with the iridium or platinum, where at least one of the aromatic heterocycle and the aryl group has an alicyclic hydrocarbon having an intramolecular carbon-carbon bridged bond as a substituent. The ability of the bulky structure of the alicyclic hydrocarbon to inhibit aggregation of the organometallic complex, concerted with the strong electron-donating property of the alicyclic hydrocarbon to the aromatic heterocycle or the aryl group, contributes to the increase in absorption coefficient and phosphorescent efficiency of the organometallic complex. The improved absorption coefficient and the phosphorescent efficiency allow the formation of a light-emitting element with excellent external quantum efficiency over 25%.
