The present invention relates to metal complexes, to compositions and formulations comprising these complexes, and to devices comprising the complexes or compositions.

Metal complexes

The invention relates to 2,2',7,7&#x2032;-tetrakis-(N,N&#x2032;-di-4-methoxy-3-methylphenylamine)-9,9&#x2032;-spirofluorene, to a process for its preparation, and to its use as hole transport material for electronic or optoelectronic devices, especially for solid-state dye-sensitized solar cells.

Hole transport material

The invention relates to formulations containing doped conductive polymers, which due to outstanding hole injection characteristics and high conductivity are very suitable for use in organic electronic devices, preferably in organic electroluminescent devices, in particular in the buffer layers thereof. Thus the invention further relates to the use of the formulations according to the invention in organic electronic devices, preferably in electroluminescent devices, in particular in the buffer layers thereof.

Formulations containing conductive polymers and use thereof in organic electronic devices

The present invention relates to compounds of the formula (1) which are suitable for use in electronic devices, in particular organic electroluminescent devices, and to electronic devices which comprise these compounds.

Materials for organic electroluminescent devices

The present invention relates to compounds of the formula (I), to mixtures of the said compounds with emitter compounds, to the use of compounds of the formula (I) and the said mixtures in electronic devices, and to electronic devices containing one or more compounds of the formula (I) and/or mixtures of compounds of the formula (I) with emitter compounds.

Materials for electronic devices

The present invention relates to compounds of the to the use of the compounds in electronic devices, to processes for the preparation of the compounds, and to electronic devices comprising the compounds, preferably as electron-transport materials, as hole-blocking materials, as matrix materials and/or as emitter materials.

The present invention relates to novel compositions comprising light emitting materials and/or charge transporting materials and one or more organic solvents having a viscosity at 25&#xb0; C. of at least 10 mPas and a boiling point of at most 400&#xb0; C., to their use as inks for the preparation of organic light emitting diode (OLED) devices, to methods for preparing OLED devices using the novel formulations, and to OLED devices prepared from such methods and formulations.

Composition having improved performance

The present invention relates to compounds having a spirobifluorene skeleton of the formula (I) for use as functional materials in electronic devices, in particular for use in the charge-transport layer and/or emission layer of organic electroluminescent devices. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to mixtures comprising the compounds according to the invention. The invention furthermore relates to the use of the compounds of the formula (I) in electronic devices and to electronic devices comprising the compounds of the formula (I).

Compounds for electronic devices

The present invention describes novel ionic metal complexes. 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. The compounds according to the invention are described by the formulae (1) and (1a).

The present invention relates to polymers which contain certain triarylamine units of the Formula (1) The materials according to the invention exhibit a longer lifetime than materials in accordance with the prior art and therefore more suitable for use in polymeric organic light-emitting diodes.

Electroluminescent polymers containing planar arylamine units, the preparation and use thereof

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 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.

White-emitting copolymers, representation, and 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 a process in which addition of certain bis(methyl)aryl compounds which have a further substituent other than hydrogen and on which at least one of the two methyl groups bears a leaving group, the molecular weight in the synthesis of poly(arylenevinylenes) is controlled reproducibly and can be deduced by the GILCH polymerization or by the sulfinyl precursor route, and to the polymers obtainable by means of the process according to the invention.

Method for controlling the molecular weight during poly(arylene vinylene) synthesis, and polymers produced therewith
