The present invention relates to compounds of formula (I), which are characterized in that they are substituted by at least one group of formula (II) and in that at least one of the substituents B1, B2, B3, B4, B5, B6, B7 and B8 represents N; a process for their production and their use in electronic devices, especially electroluminescent devices. When used as electron transport material, hole blocking material 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.
本发明涉及公式(I)的化合物,其特征在于它们至少被一个公式(II)的组取代,且B1、B2、B3、B4、B5、B6、B7和B8中的至少一个代表N;它们的生产过程以及在电子设备中的用途,特别是在电致发光设备中的用途。当在电致发光设备中作为电子传输材料、空穴阻挡材料和对磷光发射器的宿主材料使用时,公式I的化合物可能会提供改进的电致发光设备的效率、稳定性、可制造性或光谱特性。
