The present invention relates to compounds of formula (I), which are characterized in that they are substituted by benzimidazo[1,2-a]benzimidazo-5-yl and/or benzimidazo[1,2-a]benzimidazo-2,5- ylene groups 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 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.
本发明涉及式(I)的化合物,其特征在于它们被苯并咪唑[1,2-a]苯并咪唑-5-基和/或苯并咪唑[1,2-a]苯并咪唑-2,5-基取代,并且至少一个取代基B1、B2、B3、B4、B5、B6、B7和B8代表N;一种生产它们的方法以及它们在电子器件中的应用,特别是电致发光器件。当作为电致发光器件中荧光发射剂的主体材料时,式(I)的化合物可能提供电致发光器件的效率、稳定性、可制造性或光谱特性的改进。
