Abstract

The present invention relates to an organic electronic device, comprising a first electrode, a second electrode, and a substantially organic layer comprising a compound according to formula (I) between the first and the second electrode:

wherein A¹ is a C₆-C₂₀ arylene and each of A²-A³ is independently selected from a C₆-C₂₀ aryl, wherein the aryl or arylene may be unsubstituted or substituted with groups comprising C and H or with a further LiO group, provided that the given C count in an aryl or arylene group includes also all substituents present on the said group.

Claims

1. A compound according to formula (I):

2. The compound according to claim 1, wherein each of A²-A³ is independently selected from a C₆-C₁₀ aryl.

3. The compound according to claim 1, wherein the arylene is m-phenylene.

4. The compound according to claim 1, wherein A¹ is a C₆-C₂₀ arylene, wherein the C₆-C₂₀ carbons of the C₆-C₂₀ arylene also includes the carbons of all substituents present on the C₆-C₂₀ arylene.

5. The compound according to claim 4, wherein A¹ is a C₆-C₁₂ arylene.

6. The compound according to claim 1, wherein A² and A³ are phenyl.

7. The compound according to claim 1, wherein the arylene is p-arylene.
