Abstract
Official abstract text for this publication.
A heteroacene having the following formula (F) is described. An organic electroluminescence device comprises the heteroacene as a phosphorescent host, a fluorescent host, a hole blocking layer, or an electron transport layer. The heteroacene lowers a driving voltage, or increases a current efficiency or a half-life of the organic electroluminescence device.
First claim
Opening claim text (preview).
What is claimed is: 1. A heteroacene having one of the following formulas: 2. An organic electroluminescence device comprising an anode, a cathode and one or more organic layers formed between the anode and the cathode, wherein at least one of the organic layers comprises the heteroacene according to claim 1 . 3. The organic electroluminescence device according to claim 2 , wherein the organic layers comprise an emissive layer having a host, and wherein the heteroacene is comprised as the host. 4. The organic electroluminescence device according to claim 3 , wherein the host is a fluorescent host. 5. The organic electroluminescence device according to claim 3 , wherein the host is a phosphorescent host. 6. The organic electroluminescence device according to claim 2 , wherein the organic layers comprise an electron transport layer, and wherein the heteroacene of claim 1 is comprised as the electron transport layer. 7. The organic electroluminescence device according to claim 2 , wherein the organic layers comprise a hole blocking layer, and wherein the heteroacene of claim 1 is comprised as the hole blocking layer. 8. The organic electroluminescent device according to claim 2 , wherein the organic electroluminescence device is a lighting panel. 9. The organic electroluminescent device according to claim 2 , wherein the organic electroluminescence device is a backlight panel.
