Abstract
The present invention relates to an organic compound employed as a light efficiency improving layer (capping layer) material included in an organic light-emitting device. If employed in the light efficiency improving layer included in the organic light-emitting device, the compound according to the present invention can implement low-voltage driving and improved luminescent properties such as excellent luminous efficacy, color purity, and the like, and thus can be effectively used for various lighting devices and display devices.
Claims6
An organic compound represented by Formula I below:
- wherein, in Formula I above,
- X is C or Si,
- Ar1 to Ar4 are the same as or different from each other, and each independently any one selected from hydrogen, deuterium, a cyano group, a halogen group, a substituted or unsubstituted halogenated alkyl group having 1 to 20 carbon atoms, a substituted or unsubstituted halogenated alkoxy group having 1 to 20 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 20 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, and a substituted or unsubstituted heteroaryl group having 2 to 30 carbon atoms, and
- at least one of Ar1 to Ar4 is any one selected from a halogen group, a substituted or unsubstituted halogenated alkyl group having 1 to 20 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 30 carbon atoms.
An organic light-emitting device comprising a first electrode, a second electrode, and an organic layer having one or more layers disposed between the first electrode and the second electrode,
- further comprising a light efficiency improving layer (capping layer) formed on at least one side opposite to the organic layer at the top or bottom of the first electrode and the second electrode,
- wherein the light efficiency improving layer comprises the organic compound represented by Formula I above.
