By simply doping the conventional light‐emitting polymer F8BT with a helically chiral aromatic molecule , it is shown that substantial levels of CP‐electroluminescence can be generated directly. Both photoluminescent and electroluminescent emission from the polymer are observed to become circularly polarized, with the sign of the CP emission directly determined by the handedness of the dopant.
