摘要:
The present invention relates to electroluminescent devices, comprising a compound of the formula (I) as a component of the transporting/injecting and/or electron blocking layer. The compounds of formula (I) may function alone, or in combination with dopants to provide improved efficiency, driving voltage and/or lifetime of electroluminescent devices.
