Abstract

A novel light-emitting polymer containing both a highly electron-affinitive segment, biquinoline, and a good hole transporting segment, dialkoxyphenylenevinylene, was synthesized and characterized. This polymer possessed excellent film-forming properties, good thermal stability, charge injection properties and electroluminescence efficiency. A greenish-yellow light emitting diode was fabricated using this copolymer as an emitter layer.
