ABSTRACT:
The present invention provides an electrophosphorescent organic light-emitting diode (OLED). The electrophosphorescent OLED includes a substrate having a first opposing surface and a second opposing surface, a first electrode layer overlying the first opposing surface, and a light-emitting element overlying the first electrode layer. The light emitting element includes a hole injection layer and a phosphorescent emissive layer. The hole injection layer is formed of a crosslinked polysiloxane, which includes at least one siloxane unit R—Y—Siθ3/2 having at least one aromatic amine group (R) and at least one divalent organic group (Y). The aromatic amine group includes at least one of a carbazolyl group, a substituted carbazolyl group, a triarylamine group, and a substituted triarylamine group.
