Abstract
This invention relates to the development of heterocyclic materials with high triplet excitation energy, which can be used as host materials in electroluminescent devices such as a PHOLED. The materials improve the performance of such devices by enhancing the lifetime and efficiency of the device when the newly developed heterocyclic materials are utilized as a host.
