  • Anode structure for organic light emitting device
    Patent number: 6853134
    Abstract: An organic light emitting device (OLED) in which an anode includes a gold or gold composition layer under a thin layer of thiol or thiol-derivative. Preferably, the thin layer of thiol or thiol derivative is a self-assembled monolayer so as to enhance interface properties with other layers (such as a hole transporting layer) in the OLED.
