Abstract
Efficient use of organic compounds in electroluminesent devices requires detailed knowledge of their redox potential values and their ability to form stable radical ions, information available from electrochemical investigations. The electrochemical behavior of the title compounds (TH and PBD) is described, followed by the preparation of light‐emitting diodes (LEDs) based on them. The characteristics of mixed single‐layer and separated double‐layer devices presented here suggested that PBD and TH could be used for the construction of LEDs.
