Abstract

Synthesis of four coordinated gold complexes and their applications in light emitting devices thereof.

First claim

What is claimed is:

1. A compound represented by the formula:

wherein each R 1 and R 2 in (R 1 ) 2 and (R 2 ) 2 independently represents hydrogen, optionally substituted C 1 -C 4 alkyl, halogen, hydroxyl, amino, nitro, or thiol;
Y 1a represents O, S, NR 4a , wherein R 4a represents optionally substituted C 1 -C 4 alkyl; Si(R 4b ) 2 , wherein each R 4b in (R 4b ) 2 independently represents optionally substituted C 1 -C 4 alkyl; or C(R 4c ) 2 , wherein each R 4c in (R 4c ) 2 represents hydrogen or optionally substituted C 1 -C 4 alkyl;
n is an integer 0 or 1;
Y 1b , when present, represents O, S, NR 5a , wherein R 5a represents optionally substituted C 1 -C 4 alkyl; Si(R 5b ) 2 , wherein each R 5b in (R 5b ) 2 independently represents optionally substituted C 1 -C 4 alkyl; or C(R 5c ) 2 , wherein each R 5c in (R 5c ) 2 represents hydrogen or optionally substituted C 1 -C 4 alkyl;
each of Y 2a , Y 2b , Y 2c , and Y 2d independently represents N, NR 6a , or CR 6b , wherein each of R 6a and R 6b independently represents hydrogen, optionally substituted C 1 -C 4 alkyl, halogen, hydroxyl, amino, nitro, or thiol;
each of Y 3a , Y 3b , Y 3c , Y 3d , Y 3e , Y 4a , Y 4b , Y 4c , and Y 4d independently represents N, O, S, NR 6a , CR 6b , wherein each of R 6a and R 6b independently represents hydrogen or optionally substituted C 1 -C 4 alkyl; or Z(R 6c ) 2 , wherein Z is C or Si, and wherein each R 6c in (R 6c ) 2 independently represents hydrogen or optionally substituted C 1 -C 4 alkyl;

wherein m is an integer 1 or 2;
wherein the open dotted circle

indicates partial or full unsaturation of the ring with which it is associated;
provided that if m is 1, each of Y 2a and Y 2d is CH and either of Y 2b or Y 2c is N, then at least one of Y 4a , Y 4b , Y 3a , Y 3d is not N; and
provided that if n is 0, m is 2, each of Y 2a and Y 2d is CH, and either of Y 2b or Y 2c is N, then at least one of Y 3b or Y 3c is not N.

2. The compound of claim 1 , which is represented by the formula:

3. The compound of claim 1 , which is represented by the formula:

4. The compound of claim 1 , which is represented by the formula:

5. The compound of claim 1 , which is represented by the formula:

6. The compound of claim 1 , which is represented by the formula:

7. An organic light-emitting diode (OLED) comprising, as an emissive material, the compound of claim 1 .

8. An organic photovoltaic device comprising, as a donor or acceptor material, the compound of claim 1 .

9. A compound represented by the formula:

10. An organic light-emitting diode (OLED) comprising, as an emissive material, the compound of claim 9 .

11. An organic photovoltaic device comprising, as a donor or acceptor material, the compound of claim 9 .
