The interface between an inorganic electrode and an organic layer plays an important role in determining performances of organic electronic devices. In this work, a reactive self-assembled monolayer (SAM) having benzophenone (BP) terminal was prepared on an indium-tin oxide (ITO) electrode, on which a hole-transport layer of a fluorene-phenoxazine copolymer (H5) was prepared by spin-coating. Subsequent UV irradiation caused to form stable covalent bonds at the interface. It was found that a 6-nm-thick interfacial layer of H5 was stably tethered to the ITO surface. The formation of covalent bonds at the interface contributed to enhance hole injection from ITO to H5 layer. This technique was applied for preparing an organic light emitting diode (OLED), resulting in an improvement of luminescence by covalently tethering the interface between ITO and H5 hole-transport layer. |
