An unexpected phenomenon of aligning ferroelec. liquid crystal (FLC) directly in the SmC* phase is observed relatively rapidly in the presence of an ac field, by doping a small amount of an azobenzene derivative into it. There may be some interaction s between the azo compound and the FLC mols. under the a.c. field. Interactions with the rubbed polyimide surface layer may also play a role. The preliminary results show that the kinetics of this azobenzene-assisted alignment depends on the concentration of azobenzene derivative The possibility of aligning FLC mols. in the SmC* phase relatively rapidly by doping with small amounts of azo compounds and by applying an a.c. field may have some useful applications, and it provides a fairly simple method for aligning FLCs.
