Abstract

This invention relates to deuterated aryl-anthracene compounds that are useful in electronic applications. It also relates to electronic devices in which the active layer includes such a deuterated compound.

Claims (12)

1. An organic electronic device comprising a first electrical contact layer, a second electrical contact layer, and first active layer therebetween, wherein the first active layer comprises a compound selected from H1-H14, and further comprising at least one additional active layer wherein the at least one additional active layer contains a deuterated material,

2. The device of claim 1 , wherein the first active layer is an electroactive layer which further comprises an electroactive dopant compound.

3. The device of claim 2 , wherein the compound selected from H1-H14 is present in higher concentration than the electroactive dopant compound.

4. The device of claim 2 , wherein the electroactive dopant compound is selected from the group consisting of amino-substituted chrysenes and amino-substituted anthracenes.

5. The device of claim 1 , wherein the first active layer is an electroactive layer and comprises a compound selected from H1-H14 and an electroactive dopant compound.

6. The device of claim 5 , further comprising a hole injection layer between the first electrical contact layer and the first active layer.

7. The device of claim 6 , wherein the hole injection layer comprises at least one electrically conductive polymer and at least one fluorinated acid polymer.

8. The device of claim 1 , wherein the first active layer is an electroactive layer and comprises a first host material comprising compounds selected from H1-H14, a second host material, and an electroactive dopant compound.

9. The device of claim 1 , wherein the at least one additional active layer comprises a hole injection layer.

10. The device of claim 1 , wherein the at least one additional active layer comprises a hole transport layer.

11. The device of claim 1 , wherein the at least one additional active layer comprises a electron transport layer.

12. The device of claim 1 , wherein all active organic layers contain deuterated materials.
