The (E,E)-distyrylbenzenes 1a, b with terminal donor-acceptor substitution were prepared by a sequence of four reaction steps including two Wittig-Horner reactions. The products form smectic mesophases, are photostable, and should permit an electric orientation/reorientation, because of their strong dipole character.
