Abstract

Provided is an organic metal complex having a structure represented by the following general formula (1):

ML m L′ n   (1)

where: M represents a metal atom selected from Ir, Pt, Rh, Os, and Zn; L and L′, which are different from each other, each represent a bidentate ligand; m represents an integer of 1 to 3 and n represents an integer of 0 to 2, provided that m+n is 3; a partial structure ML m represents a structure represented by the following general formula (2):

and a partial structure ML′ n represents a structure including a monovalent bidentate ligand.

First claim

The invention claimed is:

1. A method of manufacturing a device, the method comprising:
preparing a substrate provided with one of an anode or a cathode;
forming an organic compound layer;
forming the other of the anode or the cathode;
wherein the organic compound layer comprises a metal complex having a structure represented by the following general formula (1):
ML m L′ n   (1)

wherein L and L′, which are different from each other, each represent a bidentate ligand;
wherein m represents an integer of 1 to 3 and n represents an integer of 0 to 2, provided that m+n is 3;
wherein M represents Ir;
wherein the partial structure ML m has a structure represented by the following general formula (8):

wherein the benzene ring with R 41 -R 44 attached thereto in the formula (8) is further represented by any one of the following formulae:

wherein *1 shows the connection to the Ir;
wherein *2 shows the connection to the benzo[f]isoquinoline ring represented in the formula (8);
wherein R 88 to R 102 , which may be identical to or different from each other, each represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted aralkyl group, an amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
wherein the partial structure ML′ n has a structure represented by any one of the following general formulae (10) to (12):

wherein R 45 to R 52 , which may be identical to or different from each other, each represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted aralkyl group, an amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and R 47 and R 48 may be bonded to form a benzene ring that is fused with the benzo[f]isoquinoline ring represented in the formula (8); and
wherein R 65 to R 79 , which may be identical to or different from each other, each represent a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, an alkoxy group, an aralkyl group, a substituted amino group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, and adjacent substituents among R 65 to R 68 may be bonded to form a ring that is fused with the benzene ring represented in the formula (10), and adjacent substituents among R 77 to R 79 may be bonded to form a ring that is fused with the backbone represented in the formula (12).

2. The method according to claim 1 , wherein the organic compound layer is formed by a vacuum deposition method, ionization-assisted deposition method, a sputtering method, a plasma method, or a coating method.

3. The method according to claim 2 , wherein the coating method is an inkjet method.

4. The method according to claim 2 , wherein the coating method is performed with binder resin.

5. The method according to claim 1 , further comprising forming a transistor connected to the anode or the cathode.

6. The method according to claim 5 , wherein the formation of the anode includes a patterning process.

7. The method according to claim 6 , further comprising forming a protective layer disposed over the device.

8. The method according to claim 7 , further comprising forming a color filter disposed over the device.

9. The method according to claim 1 , further comprising preparing a substrate; and
forming a moistureproof layer over the substrate.

10. A method of manufacturing a display apparatus, the method comprising:
forming a plurality of devices,
wherein at least one of the devices is formed by the method according to claim 1 .
