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.
