A new orientation technique for chiral smectic C phasesof ferroelectric liquid crystals (FLCs) is presented. Suppression of the helical structure in the S*C phase is achieved by dissolving an azobenzene diacrylate monomer in the FLC host. Polymerization and irradiation with linearly polarized light are then used to accomplish both induction and stabilization of FLC alignment in the S*C phase (see Figure).
