本文介绍了一种新型的基于EDOT的中性网络膜，该膜是通过原位电共聚合（ECP）形成的。结果表明，ECP膜的电导率为0.2- 0.5S·cm（-1），W（F）为4.79- 5.20eV，表面粗糙度为3.51- 5.26nm，为中性无色。以ECP薄膜作为空穴传输层的电致发光器件比PEDOT：PSS HTL器件具有更高的亮度、电流密度、效率（提高20-30%）和稳定性。与PEDOT：PSS相比，ECP膜还显著有益于相邻有机层的稳定性。这种新型的ECP薄膜为开发高性能、高稳定性的有机电致发光器件提供了更多的机会。
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.
