The present invention relates to organic electroluminescent devices, the emitting layer thereof containing a blend of a luminescent material having a narrow singlet-triplet gap and a fluorescent emission material having high steric shielding.
The present invention describes indenocarbazole derivatives having electron- and hole-transporting properties, in particular for use in the emission and/or charge-transport layer of electroluminescent devices or as matrix material. The invention furthermore relates to a process for the preparation of the compounds according to the invention and to electronic devices comprising same.
The present invention relates to organic electroluminescent devices which comprise mixtures of at least one matrix material of the formula (1) and an emitting material which has a small singlet-triplet separation.
The present invention relates to the fluorene derivatives and to organic electronic devices in which these Compounds are used as matrix material in the emitting layer and/or as hole transport material and/or as electron blocker or exciton blocker material and/or as electron transport material.
