Abstract
A compound for an organic optoelectronic device, a composition for an organic optoelectronic device including the same, an organic optoelectronic device, and a display device, the compound being represented by a combination of Chemical Formula 1 and Chemical Formula 2:
Core Innovation
The invention relates to a compound for an organic optoelectronic device. The compound is represented by Chemical Formula 1A or Chemical Formula 1B, and the structure is defined by Ar1 and Ar2, by L1 and L2, by L3, and by substituents Ra1 to Ra4 and R1 to R5. Ar1 and Ar2 are each independently a substituted or unsubstituted C6 to C30 aryl group, L1 and L2 are each independently a single bond or a substituted or unsubstituted C6 to C30 arylene group, and L3 is a substituted or unsubstituted C6 to C30 arylene group.
The substituents Ra1 to Ra4 and R1 to R5 are each independently selected from hydrogen, deuterium, a cyano group, a halogen, a substituted or unsubstituted amine group, a substituted or unsubstituted C1 to C30 alkyl group, a substituted or unsubstituted C6 to C30 aryl group, a substituted or unsubstituted C2 to C30 heterocyclic group, or a combination thereof. The disclosure further provides representative compound variants and narrower structural refinements through Chemical Formulas 1A-1, 1A-2, 1B-1, 1B-2, 1C-1, 1C-2, and other named sub-variants.
The described organic optoelectronic device includes an anode and cathode with at least one organic layer containing the compound or a composition that includes a second compound defined by Chemical Formula 3. The device may include a light emitting layer, and the organic layer(s) incorporate the compound or the composition. The document also states that the device may be used in a display device.
Claims Coverage
The claim coverage centers on the compound defined by Chemical Formula 1A or Chemical Formula 1B and on organic optoelectronic device architectures that include the compound in at least one organic layer. Three inventive features are reflected across the items, including a light emitting layer configuration.
