The present invention relates to polymers comprising structural units having partially fluorinated substituents, to mixtures and formulations comprising the polymers according to the invention, to a process for the preparation of the polymers according to the invention, and to the use of the polymers according to the invention as functional materials in electronic devices.

Materials for electronic devices

The present application relates to an electronic device comprising a heteroaromatic compound of a formula (I) as functional material, in particular as electron-transport material and as matrix material for emitter compounds. 

Electronic device

The invention relates to the use of specific glucuronolactone derivatives as self-tanning substances, as tanning enhancers for dihydroxyacetone or for a mixture of self-tanning substances comprising dihydroxyacetone, for modulation of the hue achieved in the case of tanning with dihydroxyacetone or by the mixture or preparation comprising dihydroxyacetone, as contrast-reduction agents or for coloring keratin-containing fibers, and to preparations or compositions for coloring keratin-containing fibers comprising these specific glucuronolactone derivatives.

Glucuronolactone derivatives as self-tanning substances

The invention relates to protein-adhesive dyes, to the preparation thereof and to preparations comprising same, and to a method for coloring keratin-containing fibers, in particular for coloring human hair.

Substituted quinones or analogues as colouring agents

The present invention relates to chromen-4-one derivatives of the formula (I), to the use thereof as self-tanning substance or for increasing melanin synthesis, improving melanin transport and/or improving the distribution of melanin in suprabasal layers, and to preparations comprising these chromen-4-one derivatives.

7-acyloxychromen-4-one derivatives and the use thereof as self-tanning substances

The present invention relates to cross-linkable and cross-linked polymers and to a method for the production thereof. The invention further relates to the use of said polymers in electronic devices and to the corresponding electronic devices themselves.

Crosslinkable and crosslinked polymers, method for the production thereof, and use thereof

The present invention relates inter alia to oligomers and/or polymers with functionalized side groups which are bound to the backbone of the polymer via spacer.

Polymers and oligomers with functionalized side groups

The present invention relates to polymeric materials which have electron-transporting, hole-transporting and/or emitting units in the side chains. The present invention furthermore relates to processes for the preparation of these polymers, to the use of these polymers in electroluminescent devices and to electroluminescent devices comprising these polymers.

Polymer materials for organic electroluminescent devices

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 invention relates to the use of compounds of the formula (I), in which R1, R2, m and n have the meanings indicated in the Claims, and/or physiologically acceptable salts, tautomers, stereoisomers and/or solvates thereof, including mixtures thereof in all ratios, for the inhibition of tyrosinase and for lightening the skin. The invention also relates to the use of the compounds of the formula (I) in the prophylaxis, therapy or progress control of pigment disorders of the skin. The invention furthermore relates to preparations comprising the compounds of the formula (I) in combination with at least one further active compound and to a process for the preparation of the preparations by mixing the compounds of the formula (I) with a vehicle which is physiologically acceptable for topical applications.

2,2'-furoin derivatives and use thereof to light skin

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 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 invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250&#xb0; C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques. The next layer (the organic semiconductor layer) can also be applied with the aid of different printing techniques, particularly inkjet printing, because the buffer layer is rendered insoluble by the crosslinking process, thus preventing the buffer layer from solubilizing thereafter.

Electronic devices comprising an organic conductor and semiconductor as well as an intermediate buffer layer made of a crosslinked polymer

The present invention relates to conjugated polymers and dendrimers containing styryl-triarylamine structural units, to the use thereof in electronic components, in particular in polymeric organic light-emitting diodes, to monomers for the preparation thereof, and to components and light-emitting diodes comprising polymers and dendrimers of this type.

Triarylamine-arylvinylene moiety-containing conjugated polymers, their production and use

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.
