Abstract
Specifically substituted benzofuro- and benzothienoquinolines and their use in electronic devices, especially electroluminescent devices. When used as charge transport material, charge blocker material and/or host material in electroluminescent devices, the specifically substituted benzofuro- and benzothienoquinolines may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices and reduced driving voltage of electroluminescent devices.
