The asymmetric unit of the title compound, C32H23NO2, comprises two crystallographically independent mol­ecules. In both mol­ecules, the geometries about the N atoms deviate significantly from the ideal trigonal–planar geometry with bond-angle sums about the N atom of 359.32° in one mol­ecule and 359.86° in the other. The O atoms of the carbonyl groups are deviated significantly from the central benzene rings by 0.6747 (14) and −1.1223 (13) Å in one molecule and −0.6230 (13) and 1.1559 (12) Å in the other. In the diphenyl­aniline units, the terminal phenyl rings are almost orthogonal to each other, with dihedral angles of 89.79 (9) and 89.76 (9)°. The crystal structure features C—H⋯O and C—H⋯π inter­actions.
