In recent years, organic LECs have been explored as a low-cost and color tunable displays. To increase the brightness and efficiency, we have been studied a multi host-guest LEC devices with a polymeric host. Electron push-pull fluorophores were explored as an emitter material because of the advantages of easy synthesis and processability in a thin film. An electrochemical cell was prepared with the emitting layer using the host and an electrolyte. The emission intensity and efficiency of the LEC cells were optimized using well matched HOMO and LUMO levels of host and guest materials, which allowed efficient emission by trapped charge in guest materials.
