The present invention relates to compounds according to formula (1) and/or according to formulae (4) to (10) and their use in organic electroluminescent devices, in particular as a matrix material in phosphorescent devices.

Materials for organic electroluminescent devices

The invention relates to mixtures comprising at least one polymer, additionally comprising structural units containing at least one element from the 4main group different from carbon and additionally comprising structural units that are triplet emissives. The inventive materials are better suited to the use in phosphorescent organic light emitting diodes than comparable prior art materials.

Material mixtures for use in electroluminescence

The present invention describes novel organometallic compounds which are phosphorescent emitters. Such compounds can be used as active components (=functional materials) in a variety of different applications which can in the widest sense be considered part of the electronics industry. The compounds of the invention are described by the formulae (I), (Ia), (II) and (IIa).

Rhodium and iridium complexes

The present invention relates to phosphorescent copolymers comprising trifunctional triplet emitters. The polymers according to the invention are highly soluble, readily accessible synthetically and more suitable for use in organic light-emitting diodes than are comparative materials in accordance with the prior art.

Electroluminescent polymers

The invention relates to a method for the production of high-purity, heteroleptic, orth-etallated, organometallic compounds of application as a functional material for colouring components in a wide range of applications within the widest sense of the electronics industry. A method is thus used for the cleavage of a bridged metal dimer with organometallic substances. Dihalo complexes, which may be used as monomers for polymerisations, in particular, may be produced thus.

Method for the production of heteroleptic ortho-metallated organometallic compounds

The present invention relates to a process for preparing highly pure tris-ortho-metalated organometallic compounds and to pure organometallic compounds of this type, especially compounds of the dmetals, which may find use as coloring components in the near future as active components (=functional materials) in a series of different types of applications which can be classified within the electronics industry in the widest sense.

Method for producing highly purified, tris-and bis-ortho-metallated organometallic compounds

The present invention describes novel organometallic compounds which are phosphorescence emitters. Such compounds can, as active constituents (functional materials), be used in a number of different applications, which in the broadest sense can be classed as belonging to the electronics industry. The compounds according to the invention are described by the formulas (I), (Ia), (II), (IIa), (III), (IIIa), (IV) and (IVa).

Rhodium complexes and iridium complexes

Process for the preparation of rhodium(III) and iridium(III) ketoketonates. The present invention describes a process for the preparation of rhodium and iridium compounds which are used as starting compound for various organorhodium compounds and organoiridium compounds, in which the reaction, starting from a rhodium(III) or iridium(III) salt, is carried out in at least two steps, where different solvents or solvent mixtures are used in each.

Method for producing iridium(III) keto ketonates

The present invention relates to novel organometallic compounds which are phosphorescence emitters. Such compounds can be used as active components (=functional materials) in a series of different types of application which can be classed within the electronics industry in the broadest sense. The inventive compounds are described by the formulae (1) to (32) and (1) to (8).

The present invention relates to a process for preparing highly pure tris-ortho-metallated organoiridium compounds and such pure organometallic compounds which may find use as coloring components in the near future as functional components (=functional materials) in a series of different types of applications which can be classed within the electronics industry in the widest sense.

Method for producing high-purity organoiridium compounds

The invention relates to novel metallo-organic compounds which are phosphorescence emitters. Such compounds can be used as active components (functional materials) in a range of different applications which form part of the electronics industry in the broadest sense. The inventive compounds are described by the formulae (1), (1a), (2), (2a), (3), (4), (5), (6), (7) and (8).

Palladium and platinum complexes

The present invention describes a process for preparing highly pure tris-ortho-metalled organoiridium compounds and pure organometallic compounds of this type, especially compounds of the dmetals, which may find use as coloring components in the near future as active components (=functional materials) in a series of different types of application which can be classed within the electronics industry in its broadest sense.
