Abstract:
The present invention relates to a polymer which contains at least one structural unit which has electron-transport properties, to processes for the preparation thereof and to mixtures (blends), solutions and formulations which comprise these polymers. Furthermore, the present invention relates to the use of these polymers in electronic devices, in particular in organic electro-luminescent devices, so-called OLEDs (OLED=organic light emitting diodes), and to these organic electroluminescent devices themselves. The polymers according to the invention exhibit improved efficiency, in particular on use in OLEDs.
