The ability to control alignment of liquid-crystalline molecules is very important in development of liquid crystal devices. In this study, we present a novel approach to liquid crystal alignment by means of polar thin films produced by nonmetal and metal complex salts which are [Me_APBr] and [Me_4P]_2[CdBr_4], respectively. The solid-state thin films could be readily prepared by casting a sample solution in methanol or acetonitrile onto a glass substrate. The films were then dried, and a few drops of 4'-pentyl-4-cyanobiphenyl (5CB) as nematic liquid crystal were added onto the thin films, The alignment behavior of 5CB on the surface of the polar thin films was investigated by polarizing microscopy. The preliminary result indicated that the homogeneous alignment was induced spontaneously.
