The present invention relates to a process for the vacuum purification of chemical compounds and to an apparatus for carrying out this process.

Apparatus for vacuum purification

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 the improvement of organic electroluminescent devices which consist of a certain matrix material which has been doped with at least one phosphorescent emitter, and which are characterized in that the doping zone of the emitter in the matrix at right angles to the layer extends only over a part of the matrix layer.

Organic electroluminescent element

The invention relates to a compound of the Structure 1 wherein Structure 1 contains a metal Met, coordinated to a tetradentate chelating ligand Lig of Structure 2 where V is a bridging unit which contains 1 to 40 atoms from the third, fourth, fifth and/or sixth main group and connects the two ligand moieties L1 and L2, which may be identical or different on each occurrence, covalently to one another, and where the two ligand moieties L1 and L2 satisfy Structure 3 where Cy1 and Cy2, identically or differently on each occurrence, correspond to a substituted or unsubstituted, saturated, unsaturated or aromatic homo- or heterocyclic ring, which is in each case bonded ionically, covalently or coordinatively to the metal via a ring atom or via an atom bonded exocyclically to the homo- or heterocyclic ring; and where L3, identically or differently on each occurrence, is a mono- or bidentate, neutral or monoanionic ligand, and where a is 0, 1 or 2. The present invention describes novel metal complexes with bipolar ligands. Compounds of this type can be employed as functional materials in a number of different applications which can be ascribed to the electronics industry in the broadest sense.

Metal complexes with bipodal ligands

The present invention relates to new types of material mixtures composed of at least two substances, one serving as a matrix material and the other being an emission material capable of emission and containing at least one element of atomic number greater than 20, and for their use in organic electronic components such as electroluminescent elements and displays.

Mixtures of organic emissive semiconductors and matrix materials, their use and electronic components comprising said materials

The present invention describes new metal complexes. Such compounds can be used as functional materials in a variety of different applications which can in the broadest sense be considered part of the electronics industry. The compounds of the invention have the formulae (1) and (1a).

Metal complexes and their use as the emitting constituent in electronic components, in particular in electroluminescent display devices

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 triarylamines which are substituted by defined groups. These compounds can be used for producing organic electroluminescent devices.

Materials for organic electroluminescent devices

The present invention relates to the improvement of phosphorescent organic electroluminescent devices by using materials of the formula (1), preferably triazines, pyrimidines, pyridazines and pyrazines, in the hole-blocking layer.

The invention relates to the improvement of organic electronic devices, especially organic electroluminescence devices, to which end inclusion compounds are used, especially as charge injection materials and/or charge transporting materials.

Organic electronic devices

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 invention relates to the improvement of phosphorescing organic electroluminescent devices characterized in that the emission layer, which consists of a matrix material which is doped with at least one phosphorescing emitter, directly adjoins an electrically conducting layer.

Phosphorescent organic electroluminescent device having no hole transporting layer

The present invention relates to the improvement of organic electronic devices, in particular fluorescent electroluminescent devices, by using electron-transport materials of the formula (I).

The invention relates to novel metal complexes. Said compounds can be used as functional material in a series of different applications which in the broadest sense can be attributed to the electronics industry. The inventive compounds are described by the formula (1) and by compounds (1) to (52).
