Organic Light Emitting Diode (IMAGE) Max Planck Institute for Polymer Research Caption Due to the special chemical structure, the molecules arrange themselves in a kind of spiral. The result: The electron-conducting core is shielded, which leads to higher efficiency of the organic light-emitting diode. Credit MPI-P Usage Restrictions Credit must be given to the creator.
