H. Y. Woo and co‐workers describe an energy level tuning mechanism at the interface between a metal electrode and a conjugated polyelectrolyte. On page 1100, by introducing a series of cationic conjugated polyelectrolytes, the effect of ion density on the energy level tuning process at such an interface in the organic electronic devices is investigated. These series materials indicate that two different electron injection mechanisms must be invoked according to the film thickness of the interfacial layer.
