Abstract

The present invention describes carbazole derivatives formula (1), where the following applies to the symbols used: Y is on each occurrence, identically or differently, CR or N; X is selected from C(R1)2, O, S, PR1, P(═O)R1 or BR1; characterized in that at least one group R is present which stands, identically or differently on each occurrence, for a group of the following formula (2), and/or in that at least one group R1 is present which stands for a group of the following formula (3) or (4), 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.
