Electron‐transporting materials are necessary for organic light‐emitting diodes (OLEDs) if their efficiency is going to be increased sufficiently for commercial application. Evidence is presented that the novel, electron‐deficient polymer 2,7‐poly(9‐fluorenone), see Figure, has the qualities required of an electron‐injection material in multilayer LEDs.
