| titleOfInvention | Organic light-emitting element, organometallic complex, light-emitting device, electronic appliance, and lighting device |
| abstract | The present invention relates to a phosphorescent organometallic complex, wherein the phosphorescent organometallic complex comprises a heterocyclic ring of a six-membered ring having a nitrogen atom; Iridium or platinum to which the nitrogen atom is coordinated; And an aryl group which is bonded to the? Carbon atom of the nitrogen atom and is ortho-metallated with iridium or platinum, and at least one of the aromatic ring and the aryl group is substituted with aliphatic cyclic carbonyl It has hydrogen. The ability of the bulky structures of aliphatic cyclic hydrocarbons to block the association of the organometallic complexes in cooperation with the electron donating groups of the aliphatic cyclic hydrocarbons with respect to the heterocyclic ring or the aryl groups is determined by the absorption coefficient of the organometallic complex and the phosphorescent efficiency . ≪ / RTI > Improved absorption coefficient and phosphorescent efficiency allow formation of light emitting devices with excellent external quantum efficiency exceeding 25%. |
