Abstract

The present invention relates to novel polymers comprising a repeating unit of the formula (I) and their use in electronic devices. The polymers according to the invention have excellent solubility in organic solvents and excellent film-forming properties. In addition, high charge carrier mobilities and high stability of the emission color can be observed, if the polymers according to the invention are used in organic light emitting diodes (OLEDs).
