Compound, material for organic electroluminescent element, organic electroluminescent element and electronic device

Specific polycyclic compounds of the general formula (I) and a process for its preparation, an electronic device comprising at least one of these compounds, an emitting layer, preferably present in an electronic device, comprising at least one compound of general formula (I) and the use of compounds according to general formula (I) in an electronic device as a host material, a charge transporting material, charge and/or exciton blocking material, preferably as a host material or an electron transporting material.

Organic light emitting device and compounds for use in same

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.
