3‐Cyano‐9‐diarylamino carbazoles have been synthesized. These new compounds emit in the blue to green region. Double‐layer electroluminescent devices using these compounds as the hole‐transport/emitting materials are highly efficient. Two of the compounds can be fabricated into single‐layer devices with good performance. Green‐ and blue‐emitting devices with good performance were also fabricated using one of the compounds as the hole‐injection layer.
