Abstract
Official abstract text for this publication.
The present invention relates to a depositable ionic organic functional material having a structure selected from the formulas (21) to (26). The depositable ionic organic functional material can be used in high-efficiency blue to red OLEDs. The present invention also relates to an organic electroluminescent device using the depositable ionic organic functional material as a dopant in the organic light-emitting layer thereof.
First claim
Opening claim text (preview).
What is claimed is: 1. A depositable ionic organic functional material, wherein the depositable ionic organic functional material has a structure selected from the following formulas (21) to (26): 2. A method of using the depositable ionic organic functional material according to claim 1 in an organic electroluminescent device comprising: doping the depositable ionic organic functional material as a dye in an organic light-emitting layer of the organic electroluminescent device. 3. An organic electroluminescent device, comprising a substrate, and an anode layer, an organic light-emitting functional layer, a cathode layer formed in sequence upon the substrate, wherein the organic light-emitting functional layer comprises a hole transport layer, an organic light-emitting layer, and an electron transport layer, wherein a host material of the organic light-emitting layer is doped with the depositable ionic organic functional material according to claim 1 . 4. The organic electroluminescent device according to claim 3 , wherein a doping concentration of the depositable ionic organic functional material is 2 wt % 10 wt % of the total weight of the organic light-emitting layer. 5. The organic electroluminescent device according to claim 3 , wherein the depositable ionic organic functional material is a red, yellow, green, or blue light emitting material. 6. The organic electroluminescent device according to claim 3 , wherein the organic light-emitting layer has a thickness of 10 nm 50 nm. 7. The organic electroluminescent device according to claim 6 , wherein the organic light-emitting layer has a thickness of 10 nm-30 nm.
