Paper Abstract

One of the themes that has emerged in the field of organic light emitting devices (OLEDs) is the importance of developing materials that form robust films, capable of undergoing wet and dry processing conditions. It is through such characteristics that polymers may have unique opportunities in the effective and inexpensive study of novel single and double layer thermosetting and solvent soluble polymer light emitting devices based on triarylamines for hole transport layer and compounds possessing the blue emitting 9,9-dialkylfluorene unit for the emitting and electron transport layer. These devices possess high thermal stability, high quantum efficiency, and high bandgap emission. We fabricated dot matrix displays based on analogs of these materials where cathode separation was achieved 'in situ' by a resist structure with reentrant wall profile that was built on top of the EL layers. This is a demonstration that polyfluorenes are robust and compatible with standard resist processing.
