A novel conjugated neutral surfactant poly[9,9‐bis(6′‐(diethanolamino)hexyl)fluorene] (PFN‐OH; see figure) has been developed as an efficient electron‐injection material for fabricating highly efficient multilayer polymer light‐emitting diodes. Compared to the traditional neutral surfactants used, PFN‐OH possesses the combined advantages of good conductivity and excellent electron‐injection ability from high‐work‐function metals (e.g., Al, Ag, or Au).
