Abstract
Provided are an organic electroluminescent material and a device comprising the same. The organic electroluminescent material is a novel compound having a parent core structure formed by fusing indole and pyrrole with an azamacrocycle and bonded with benzoquinazoline or benzoquinoxaline and similar structures thereof. The organic electroluminescent material may be used as a host material in an electroluminescent device. The novel compound can provide better device performance in the electroluminescent device. Further provided are an electroluminescent device and a compound formulation.
