10. The host LC was racemic 2-[4-(6-methyl-l-octyloxy)phenyl]5-octylpyrimidine. The phase transition temperatures were Cr 3 SmC 47.6 SmA 58.2 Iso.
11. Before photoirradiation, FLCs were always aligned by applied voltage, and the polarizers were adjusted so that the transmittance of the probe light become zero.
12. Phase assignment is based on the microscope observation of the texture as well as the insensitive behavior to applied voltage.
