The present invention relates to electronic devices, especially electroluminescent devices, comprising compounds of formula (I), and/or (II), especially as host for phosphorescent emitters, electron transporting materials, or emitter materials. The hosts may function with phosphorescent materials to provide improved efficiency, stability, manufacturability, or spectral characteristics of electroluminescent devices.
