Abstract

The present invention relates to electronic devices comprising organic semiconductors whose content of halogens is less than 20 ppm. This increases the lifetime and the efficiency of the corresponding electronic devices, and these materials are thus better suited to use in organic electronic devices than materials with a higher halogen content. The present invention further relates to corresponding organic semiconductors and to a process for their production.
