Synthesis and Characterization of Novel Conjugated Light-Emitting Polymers

Abstract

Novel fluorene-based conjugated light-emitting polymers have been designed and synthesized. By varying the compositions of the polymer backbone, the charge-injecting and -transporting properties of the polymers were significantly improved. The light-emitting diodes (LEDs) using these polymers as the emissive layers exhibited low turn-on voltage, a high external quantum efficiency, and high brightness due to balanced electron and hole conductivity.
