2,5-Bis{2,2-bis[4-(dimethylamino)phenyl]ethenyl}-N,N′-diphenyl-N,N′-dipropylbenzene-1,4-diamine

The title compound, C60H68N6, was prepared by Horner olefination of a terephthaldialdehyde and a diarylmethyl phosphonate. There is one half-molecule, located on an inversion centre, in the asymmetric unit. The dihedral angle between the plane of the vinylene unit and the central ring is 36.79 (15)°, while those between the vinylene unit and the lateral phenyl rings are 53.04 (10) and 53.74 (9)°.
