The present invention relates to electronic devices comprising organic semiconductors whose content of halogens is less than 20 ppm. This increases the lifetime and the efficiency of the corresponding electronic devices, and these materials are thus better suited to use in organic electronic devices than materials with a higher halogen content. The present invention further relates to corresponding organic semiconductors and to a process for their production.

Electronic devices containing organic semi-conductors

The present invention relates to organic semiconductors which contain structural units L=X and in addition structural units which emit light from the triplet state. The materials according to the invention are more soluble and easier to synthesise and are therefore more suitable for use in organic light-emitting diodes than comparative materials in accordance with the prior art.

Materials for electroluminescence and the utilization thereof

The present invention relates to the improvement of organic electroluminescent devices, in particular blue-emitting devices, by using compounds of the formula (1) as host materials in the emitting layer.

Phenanthrene derivative

The present invention relates to white-emitting copolymers which are obtained by a combination of blue-, green- and red-emitting repeating units. The copolymers of the invention display better film formation and an improved efficiency when used in polymeric organic light-emitting diodes compared to materials according to the prior art.

White-emitting copolymers, representation, and use thereof

The present invention relates to polymers which contain novel structural units of the formula (I). The materials according to the invention exhibit improved efficiency and a longer lifetime on use in a polymeric organic light-emitting diode.

Electroluminescent polymers and the use thereof

The present invention relates to conjugated polymers which contain specific fused arylamine structural units. The inventive materials have improved efficiency at a high illumination density and are therefore suitable in particular for use in what are known as passive matrix displays.

Conjugated polymers containing arylamine units, the representation thereof and the use of the same

The present invention relates to electroluminescent polymers which contain structural units of the formula (1) and to the use thereof. The polymers according to the invention exhibit improved efficiency and a longer lifetime, in particular on use in polymeric organic light-emitting diodes.

Electroluminescent polymers and use thereof

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 invention relates to conjugated polymers containing novel structural units according to formula (1). The inventive materials are characterized by increased efficiency and a longer service life when used in polymer organic light emitting diodes.

Conjugated polymers containing dihydrophenanthrene units and use thereof

White-emitting copolymers, representation and use thereof

The present invention relates to organic semiconductors which contain structural units L=X and in addition structural units which emit light from the triplet state. The materials according to the invention are more soluble and easier to synthesize and are therefore more suitable for use in organic light-emitting diodes than comparative materials in accordance with the prior art.

The present invention relates to novel conjugated polymers comprising spirobifluorene units and their use in optoelectronic devices, preferably in, for example, displays based on polymeric organic light-emitting diodes.

Conjugated polymers containing spirobifluorene units and the use thereof

The present invention relates to novel polymers which comprise spirobifluorene and fluorine units of the formulae (I) and (II) and may further comprise additional structural elements which may have charge transport properties, hole transport properties and/or electron transport properties. Such materials display a significantly improved property profile in electronic components, particularly when used in a PLED, in particular as electroluminescence material, in organic integrated circuits (O-ICs), organic field effect transistors (OFETs), organic thin film transistors (OTFTs), organic solar cells (O-SCs) or organic laser diodes (O lasers).
