Summary: | The present invention relates to novel polymers which comprise one or more recurring units selected from spirobifluorene, indenofluorene, phenanthrene, dihydrophenanthrene, dihydropyrene, tetrahydropyrene and dihydrobenzoxepine derivatives and have low polydispersity and a high molecular weight, to a process for the preparation thereof, to blends and formulations comprising these polymers, and to the use of these polymers in electronic devices, in particular in organic light-emitting diodes, so-called OLEDs (OLED=organic light-emitting diode). |
