Anionic conjugated polyelectrolyte–wetting properties with an emission layer and free ion migration when serving as a cathode interface layer in polymer light emitting diodes (PLEDs)†
Abstract
A novel anionic conjugated polyelectrolyte combined with polyfluorene backbone, sulfonate sodium and PEO derivatives in the side chains (PFEOSO3Na) shows super wetting properties on hydrophobic F8BT layers and excellent electron injection properties.
