Arrays of small polymer‐based LEDs have been produced using a technique based on polymer self‐organization. The active component, a polybithiophene, is shown to form small (50–200 nm) islands in a PMMA matrix when the two materials are mixed in an appropriate ratio. These islands become light emitters when electron‐ and hole‐injecting contacts are applied. The generation of the arrays is described and the use of polymer‐based hole‐injecting contacts, which provide mechanical flexibility, is discussed.
