The present invention describes carbazole, dibenzofuran, dibenzothiophene and fluorene derivatives which are substituted by electron-deficient heteroaryl groups, in particular for use as triplet matrix materials in organic electroluminescent devices. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to electronic devices comprising these compounds.

Materials for organic light emitting devices

The present invention relates to copolymers, particularly to copolymers comprising a photoactive unit, the copolymers being particularly suitable for ophthalmic devices. The copolymers include one or more different polymer units in addition to the photoactive unit, such as polymerized units derived from ethylene, propylene, an acrylate, a methacrylate, or a styrene.

Compounds for optically active devices

The application relates to compounds having functional substituents in a specific spatial arrangement, to devices comprising same, and to the preparation and use thereof.

Materials for electronic devices

The invention relates to materials, to electroluminescence devices comprising said materials and to the use thereof.

Substituted oxepines

The present invention relates to novel compounds, particularly to compounds comprising a photoactive unit, said novel compounds being particularly suitable for compositions and ophthalmic devices as well as to compositions and ophthalmic devices comprising such compounds.

Hydrophobic compounds for optically active devices

The present invention relates to spiro compounds containing electron-conducting groups and to electronic devices, in particular organic electroluminescent devices, comprising these compounds.

Heterocyclic spiro compounds

The present invention relates to a composition for ophthalmological products, to corresponding copolymers and the preparation thereof and to the use thereof for the production of ophthalmic lenses or ophthalmological implants and to these products.

Composition for ophthalmological products

The present invention describes dibenzofuran and dibenzothiophene derivatives, in particular for use as triplet matrix materials in organic electroluminescent devices. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to electronic devices comprising same.

Materials for organic electroluminescent devices

The present invention relates to compounds which are suitable for use in electronic devices, and to electronic devices, in particular organic electroluminescent devices, comprising these compounds. The compounds have a dibenzofuran, dibenzothiophene or a fluorene group substituted in the 1-position, either directly or through a linking group, to a carbon atom of a heteroaromatic group with one or two nitrogen atoms in a bicyclic 6/6 core, or to a carbon or nitrogen atom of a heteroaromatic group with two nitrogen atoms in a bicyclic 5/6 core and is further substituted with a group selected from dibenzofuran, dibenzothiophene, fluorene or carbazole.

The present invention relates to novel compounds, particularly to hydrophilic compounds, comprising a photoactive unit, said novel compounds being particularly suitable for ophthalmic devices. The present application also relates to ophthalmic devices comprising such compounds.
