Work functions of gold and silver are varied by over 1.4 and 1.7 eV, respectively, by using self‐assembled monolayers. Using these modified electrodes, the hole current in a poly(2‐methoxy‐5‐(2′‐ethylhexyloxy)–1,4‐phenylene vinylene) light‐emitting diode is tuned by more than six orders of magnitude (see Figure). Suppression of the hole current enables measurement of the electron current in a polymer/polymer blend photovoltaic cell.
