Abstract

Provided are organic metal compounds in which compounds for host and compounds for dopant are connected, organic electroluminescence display devices using the compounds and a method for preparation of the devices. Also provided are organic metal compounds in which compounds for host and compounds for dopant where connected to make energy transmission between host and dopant possible at a molecular level, an organic electroluminescence display device using the same and a preparation method thereof.

Claims (10)

1. An organic metal compound having the following structure:

2. An organic metal compound having the following structure:

3. An organic electroluminescence device comprising an organic layer in between a pair of electrodes, wherein the organic layer contains the organic metal compound of claims 1 or 2 .

4. The organic electroluminescence device as set forth in claim 3 , wherein the organic layer is an emitting layer.

5. A preparation method for an organic electroluminescence device comprising the following steps:

forming a first electrode on a substrate;

forming an organic layer on the first electrode;

and forming a second electrode on the organic layer, wherein the organic later is formed by doping the organic metal compound of claims 1 or 2 .

6. The preparation method for an organic electroluminescence device as set forth in claim 5 , wherein the first electrode is an anode, the second electrode is a cathode, and the organic layer is an emitting layer.

7. The preparation method of the organic electroluminescence device as set forth in claim 5 , wherein the organic layer is formed by a wet process.
