| abstract | The present invention relates to a phosphorescent organometallic complex, which includes a six-membered heteroaromatic ring having a nitrogen atom; Iridium or platinum coordinated by the nitrogen atom; And an aryl group bonded to the α carbon atom of the nitrogen atom and ortho-metalized with iridium or platinum, and at least one of the multi-aromatic ring and the aryl group has a carbon-carbon crosslinking bond in the molecule as a substituent. Has hydrogen. The ability of the bulky structures of aliphatic ring hydrocarbons to prevent the association of organometallic complexes, in cooperation with the electron donating of aliphatic ring hydrocarbons to the heteroaromatic ring or to the aryl group, results in an absorption coefficient and phosphorescence efficiency of the organometallic complex. Contribute to increase. The improved absorption coefficient and phosphorescent efficiency allow for the formation of light emitting devices with good external quantum efficiency of over 25%. |
