Derivatized electrodes in the construction of organic light emitting diodes



Overcoming the disadvantages of organic light-emitting diodes (LEDs) is important if full advantage is to be taken of their benefits. It is shown that a significant increase in durability and decrease of the turn-on operating field can be achieved by attaching the electroactive polymer to the metal-oxide electrode chemically. The Figure shows a single-layer LED device with an electrode derivatized with a functionalized oligophenylene layer.
