摘要：
New azaindolocarbazole compounds are disclosed, which can be used as hosts in an organic electroluminescent device. Compared to existing host materials, the compounds can effectively modulate the charge transporting properties in host materials and give OLEDs better performance. An electroluminescent device and a formulation are also disclosed.
