Abstract

Novel metal complexes containing silyl substitution are provided. Depending on the location of the substitution, compounds that emit in the yellow or green portions of the spectrum can be produced. These compounds are useful as components of OLED devices.

First claim

The invention claimed is:

1. A compound selected from the group consisting of:

2. The compound of claim 1 , wherein the compound is

3. The compound of claim 1 , wherein the compound is

4. The compound of claim 1 , wherein the compound is

5. The compound of claim 1 , wherein the compound is

6. A first device comprising a first organic light emitting device, the first organic light emitting device comprising:
an anode;
a cathode; and
an organic layer, disposed between the anode and the cathode, comprising a compound of claim 1 .

7. The first device of claim 6 , wherein the first device is selected from the group consisting of a consumer product, an organic light-emitting device, and a lighting panel.

8. The first device of claim 6 , wherein the organic layer is an emissive layer and the compound is an emissive dopant.

9. The first device of claim 6 , wherein the organic layer is an emissive layer and the compound is a non-emissive dopant.

10. The first device of claim 6 , wherein the organic layer further comprises a host.

11. The first device of claim 10 , wherein the host comprises a triphenylene containing benzo-fused thiophene or benzo-fused furan;
wherein any substituent in the host is an unfused substituent independently selected from the group consisting of C n H 2n+1 , OC n H 2n+1 , OAr 1 , N(C n H 2n+1 ) 2 , N(Ar 1 )(Ar 2 ), CH═CH—C n H 2n+1 , C≡C—C n H 2n+1 , Ar 1 , Ar 1 —Ar 2 and C n H 2n —Ar 1 ;
wherein n is from 1 to 10; and
wherein Ar 1 and Ar 2 are independently selected from the group consisting of benzene, biphenyl, naphthalene, triphenylene, carbazole, and heteroaromatic analogs thereof.

12. The first device of claim 10 , wherein the host is selected from the group consisting of:

and combinations thereof.

13. The first device of claim 10 , wherein the host comprises a metal complex.
