Samsung patents boron compound for brighter OLED screens
Samsung describes a new chemical mixture for organic light-emitting diodes (OLEDs), which are the displays used in phones and TVs. The invention combines a specific boron-based compound with a phosphorescent material to create the screen's light-emitting layer.
In the filing’s own words
Provided are a composition for an organic electroluminescent device, the composition including a boron compound represented by Formula 1 and a phosphorescent material, an organic electroluminescent device including the composition, and a boron compound represented by Formula 1: wherein, in Formula 1, R 11, R 12, R 13, R 14, R 21, R 22, R 23, R 24, R 31, R 32, R 33, R 34, R 41, R 42, R 51, R 52, R 53, R 54, R 55, R 6, Ar, m, and n are each as defined in the specification.
What exactly they claim (claim 1)
1. A composition for an organic electroluminescent device, the composition comprising a boron compound represented by Formula 1 and a phosphorescent material: wherein, in Formula 1, R 11, R 12, R 13, R 14, R 21, R 22, R 23, R 24, R 31, R 32, R 33, R 34, R 41, R 42, R 51, R 52, R 53, R 54, R 55, and R 6 are each independently a hydrogen atom, a cyano group, a halogen atom, a deuterium atom, a substituted or unsubstituted aryl group, a substituted or unsubstituted heteroaryl group, a substituted or unsubstituted diarylamino group, a substituted or unsubstituted diheteroarylamino a group, substituted or unsubstituted arylheteroarylamino group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted heteroaryloxy group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted heteroarylthio group, or a linker, each Ar is independently a substituted or unsubstituted benzene ring, or a substituted or unsubstituted heteroaromatic ring having 5 or 6 ring-forming atoms, wherein Ar optionally comprises a linker, m is an integer from 0 to 4, n is an integer from 1 to 5, and a sum of m and n is 5, the linker is a single bond or a linking group, and ring 3 and ring 6 are not bonded together via the linker, ring 3 and Ar are not bonded together via the linker, ring 4 and ring 6 are not bonded together via the linker, and ring 4 and Ar are not bonded together via the linker.
