摘要:
The present invention relates to heteroleptic complexes, comprising a phenylimidazole or phenyltriazole unit bound to a central metal atom by a carbene bond, and phenylimidazole ligands, which are bound to the central atom by a nitrogen metal bond, to OLEDs containing such heteroleptic complexes, to light-emitting layers containing at least one such heteroleptic complex, to a device selected from the group consisting of lighting elements, stationary screens and mobile screens containing such an OLED, to the use of such a heteroleptic complex in OLEDs, for example as an emitter, matrix material, charge transport material and/or charge blocker.
摘要:
The present invention relates to compounds of formula (I), a process for their production and their use in electronic devices, especially electroluminescent devices. When used as electron transport and/or host material for phosphorescent emitters in electroluminescent devices, the compounds of formula I may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
