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 conjugated polymers comprising specific carbazole structural units. The materials according to the invention display steeper current-voltage curves and are therefore better suited to use in organic light-emitting diodes than are comparative polymers which do not contain these units.

Conjugated polymers and blends containing carbazole, representation and use thereof

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.

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).

Conjugated polymers containing spirobifluorene units and fluorene units, and the use thereof

The present invention relates to a process for preparing aryl-aryl-coupled compounds and materials. These materials play an important role in industry, for instance as liquid crystals, pharmaceuticals, agrochemicals and as organic semiconductors. The aryl-aryl couplings hitherto carried out by means of Yamamoto coupling require specific additives in order to give a product suitable for the subsequent use. Particularly in the electronics industry, the Yamamoto coupling needs to meet particular requirements.

Method for the production of aryl-aryl coupled compounds

The invention relates to the preparation of aryl-aryl coupled compounds and materials. These materials play an important role in industry, for example as liquid crystals, pharmaceuticals and agrochemicals, to mention just a few application areas. These compounds, in particular, are also of major importance especially in the high-growth area of organic semi-conductors (for example, applications in organic or polymeric light-emitting diodes, organic solar cells, organic ICs).
