The invention relates to dimeric copper(I) complexes according to formula A, in particular as emitters in optoelectronic devices such as organic light emitting diodes (OLEDs) and other devices wherein:

Singlet harvesting with dual-core copper (I) complexes for optoelectronic devices

The invention relates to an optoelectronic component having a copper(I) complex of the formula: wherein X is independently selected from Cl, Br and I; N*&#x2229;E or E&#x2229;N* is a bidentate ligand connected to a first Cu atom via an N atom and connected to a second Cu atom via an E group, or a monodentate ligand connected to a Cu atom via an E group, wherein E is RAs or RP, wherein R is selected from alkyl, aryl, alkoxy, and phenoxy; N* is a part of an aromatic group comprising an imine functional group, wherein the aromatic group is selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl, imidazolyl, and fused N-heteroaromatics, and wherein the imine functional group comprises the N atom double bonded to a carbon atom of the aromatic group; and &#x2229; is a carbon atom, which is likewise part of the aromatic group, connected to the N atom of said aromatic group and also connected to the E group via the As or P atom of the E group.

Copper complexes for optoelectronic applications

The invention relates to gold(I) complexes having a planar-trigonal coordination geometry and multivalent ligands for use in an optoelectronic device, in particular in organic light-emitting diodes (OLEDs) and in light-emitting electrochemical cells (LEECs).

Use of gold complexes in optoelectronic devices

The invention relates to copper(I) complexes of the formula A wherein X=Cl, Br or I (independently of one another); N*&#x2229;E=a bidentate ligand, wherein E=a phosphinyl group including a phosphorus atom or an arsenyl group including an arsenic atom, wherein the phosphinyl group or the arsenyl group is combined with R in the form of RE (where R=alkyl, aryl, alkoxy, or phenoxy; N*=imine function which is part of an aromatic group selected from pyridyl, pyrimidyl, pyridazinyl, triazinyl, oxazolyl, thiazolyl and imidazolyl, the aromatic group optionally having at least one substituent to increase the solubility of the copper(I) complex in an organic solvent; and &#x2229;=at least one carbon atom which is likewise part of the aromatic group. The carbon atom is located directly adjacent both to the imine nitrogen atom, coordinating to Cu in the case of a bridging ligand and to the phosphorus or arsenic atom. The invention also relates to the use of the copper(I) complexes in optoelectronic assemblies, especially in Organic Light Emitting Diodes (OLEDs).
