Bright, balanced white‐light electroluminescence has been achieved from a single active oligothiophene compound. White light is created by the superposition of a broad blue–green‐light emission originating from the single molecule and a red‐shifted narrow peak due to dimer formation. These results open the way to the fabrication of novel, low‐cost white‐light‐emitting devices with a single molecular material as the active compound.
