摘要：

Bright, balanced white-light electro-luminescence 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.
