Abstract:
This contribution presents a kind of novel and neutral network films based on EDOT formed by in situ electrocopolymerization (ECP). The ECP films which are neutral and colorless exhibit the conductivity of 0.2-0.5 S·cm(-1), W(F) of 4.79-5.20 eV, and RMS roughness of 3.51-5.26 nm. The electroluminescent devices where ECP films acted as hole-transport layer (HTL) exhibit higher brightness, current density, efficiency (20-30% improvement), and stability than that of PEDOT:PSS HTL device. The ECP films also significantly benefit the stability of neighboring organic layer compared to PEDOT:PSS. This kind of new ECP films affords more opportunities to develop organic light-emitting diodes (OLEDs) with high performances and stability.
