【文章名】Conjugated Zwitterionic Polyelectrolytes and Their Neutral Precursor as Electron Injection Layer for High-Performance Polymer Light-Emitting Diodes
[摘要]:Conjugated zwitterionic polyelectrolytes with free mobile ions, good alcohol solubility, and excellent electron injection ability are developed. PLEDs based on a Al cathode with a conjugated zwitterionic polyelectrolytes electron injection layer show more than 70 times higher efficiency than that of bare Al cathode devices.
