Abstract
In the title mol-ecule, C48H33N, the central N atom shows no pyramidalization, so that the N atom and the three C atoms bound to the N atom lie almost in the same plane. The three para-phenyl-ene rings bonded to the N atom are in a propeller form. All of the naphthalene ring systems are slightly bent. In the crystal, mol-ecules form an inversion dimer, through two pairs of C-H⋯π inter-actions, which further inter-acts with the adjacent dimer via another two pairs of C-H⋯π inter-actions, forming a column structure along the a axis. There are no significant inter-actions between these column structures.

Summary
Triarylamines (TAAs) having various substituents at their para-positions are widely known to give the corresponding stable cation radicals upon chemical or electrochemical one electron oxidation (Seo et al, 1966). -Extended TAAs with extra aromatic rings at the periphery have received considerable attention as key components in the fields of organic electroluminescence devices. Triarylamines (TAAs) having various substituents at their para-positions are widely known to give the corresponding stable cation radicals upon chemical or electrochemical one electron oxidation (Seo et al, 1966). -Extended TAAs with extra aromatic rings at the periphery have received considerable attention as key components in the fields of organic electroluminescence devices. The title compound was first synthesized by Kwon et al (2010) as a hole-transporting material in organic light-emitting diodes. Phosphorescent organic light-emitting diodes were reported by using the title compound as the hole-transporting material (Krucaite et al, 2019). No crystal structure of this compound has been reported. We report the crystal structure of the title compound.
