Abstract

The present invention describes novel indenofluorene derivatives which can preferably be employed as matrix materials for phosphorescent dopants or as electron-transport materials, in particular for use in the emission and/or charge-transport layer of electroluminescent devices. The invention furthermore relates to polymers which comprise these compounds as structural units and to a process for the preparation of the compounds according to the invention and to electronic devices which comprise same.
