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 present invention describes diazadibenzofuran or diazadibenzothiophene derivatives substituted by carbazole, fluorene, phenanthrene, benzofuran and/or benzothiophene 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.

Compounds with diazadibenzofurane or diazadibenzothiophene structures

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.
