The title compound, C30H18ClNO, is a product of the condensation reaction of acenaphthylene-1,2-dione and 5'-chloro-1,1':3',1''-terphenyl-4'-amine. The acenaphthylene fragment and two terminal phenyl rings are rotated relative to the central benzene ring by 72.2 (3), 43.2 (3) and 41.2 (3)°, respectively. This molecular conformation is supported by weak C-H interactions. In the crystal, molecules form centrosymmetric dimers by the stacking interactions between two neighboring acenaphthylene fragments, with an interplanar distance of 3.365 (3) Å. The dimers are bound to each other by weak C-HN and C-H interactions, forming a three-dimensional framework.
