摘要：
The present invention relates to organic light emitting devices (OLEDs), and more specifically to efficient OLEDs having electron blocking layers. The devices of the present invention comprise at least one electron blocking layer which functions to confine electrons to specific regions of the light emitting devices. The present invention also relates to materials for use as electron blockers that show increased stability when incorporated into an organic light emitting device.
