The present invention describes dibenzofuran derivatives substituted by electron-deficient heteroaryl groups, and electronic devices, especially organic electroluminescent devices, comprising these compounds as triplet matrix materials.

Materials for organic electroluminescent devices

The present invention relates to a composition which comprises an electron-transporting host and a hole-transporting host, to the use thereof in electronic devices and to electronic devices containing this composition. The electron-transporting host is particularly preferably selected from the class of the triazine-dibenzofuran-carbazole systems or the class of the triazine-dibenzothiophene-carbazole systems. The hole-transporting host is preferably selected from the class of the biscarbazoles.

Composition for organic electronic devices

The invention relates to organic electroluminescence devices containing indone carbazole derivatives.

Organic electroluminescence devices

The present invention relates to compounds of formula (I), to processes for producing the compounds, and to electronic devices containing at least one compound of formula (I).

Compounds for electronic devices

The present invention describes nitrogen-containing heterocycles substituted by carbazole groups, especially for use in electronic devices. The invention further relates to a process for preparing the compounds of the invention and to electronic devices comprising these.
