摘要

摘要采用单阴离子导体(SAC)改善铝阳极/SAC/聚[2-甲氧基-5-(2 ' -(乙基己氧基)-1,4-苯基乙烯]发射层/氧化铟锡阴极器件的空穴注入性能。由于软嵌段在SAC聚合物链上良好的链段运动，使得离子空间电荷在阳极附近积累，因此SAC具有优异的注孔性能。因此，可以实现电子-空穴对的平衡注入，从而大大提高量子效率。

Use of a Single Anionic Conductor as a Hole-Injecting Material for Polymer Light-Emitting Diodes

Abstract A single anionic conductor (SAC) was employed to improve the hole injection properties in an Al anode/SAC/poly[2-methoxy-5-(2′-(ethylhexyloxy)-1,4-phenylenevinylene) emissive layer/indium tin oxide cathode device. The SAC possesses an excellent hole-injection property, because of ionic space charge accumulation near the anode by the good chain segmental motion of the soft block in the polymer chains of the SAC. Thus, a balanced injection of an electron-hole pair can be achieved to greatly improve the quantum efficiency.
