4H-Imidazo[1,2-a]imidazoles for Electronic Applications

The present invention relates to compounds of formula 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.

4H-IMIDAZO[1,2-A]IMIDAZOLES FOR ELECTRONIC APPLICATIONS

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 host material for phasphorescent emitters in electroluminescent devices, the compounds of formula (I) may provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
