Optically aligned ferroelectric liquid crystals
A new orientation technique for chiral smectic C phases of 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 use to accomplish both induction and stabilization of FLC alignment in the S*(C) phase (see Figure).
