A novel compound, 5,7,14,16‐tetraphenyl‐8:9,12:13‐bisbenzo‐hexatwistacene ( TBH ), has been successfully synthesized through a retro‐Diels–Alder reaction. Single‐crystal structure analysis indicated that TBH has a twisted configuration with a torsion angle of 27.34°. The HOMO–LUMO gap of TBH calculated from the difference between the half‐wave redox potentials (E 1/2 ox =+0.40 eV and E 1/2 red =−1.78 eV) is 2.18 eV, which is in good agreement with the band gap (2.19 eV) derived from the UV/Vis absorption data. In addition , organic light‐emitting devices using TBH as emitter have been fabricated. The results revealed that TBH is a promising red light‐emitting candidate for applications in organic light‐emitting diodes.
