An asymmetric twistacene, 1′,4′‐diphenyl‐naphtho‐(2′.3′:1.2)‐pyrene‐6′‐nitro‐7′‐methyl carboxylate (tetracene 2 ), was synthesized by using benzyne‐trapping chemistry. Its structure, determined by X‐ray crystallography, confirmed that this material has a twisted topology with torsion angles as high as 23.8(3)°. Organic light‐emitting devices using tetracene 2 as either charge‐transporting materials or emitters have been fabricated. The results indicate that this material has bipolar transporting behavior in these devices.
