摘要

The title compound, C26H20N2, was obtained during a search for new π-extended ligands with the potential to generate efficient phosphors with iridium(III) for organic light-emitting devices (OLEDs). The benzoquinoxaline ring system is almost planar (r.m.s. deviation = 0.076 Å). A pseudo-twofold rotation axis runs through the midpoints of the C2—C3 and C9—C10 bonds. The two phenyl rings are twisted relative to the benzoquinoxaline ring system, making dihedral angles of 53.91 (4) and 36.86 (6)°. In the crystal, C—H⋯π (arene) inter­actions link the mol­ecules, but no π–π inter­actions between aromatic rings are observed.
