The orienting ability of different ate-dyes has been investigated in Rims organized by individual dyes or by mixtures of a dye either with polyamide acid or with a specially synthesized dopant based on phenylquinoxalinone as well([1]). It was shown that the replacement of the functional group in the ate-dye molecules plays a very important role in the appearance or disappearance of the photo-anisotropy. The orienting films always were prepared using the spin-coating technique. Sometimes, the appearance of either planar or homeotropic orientation was dependent only on the solvent used during the spin-coating procedure. In all cases there was a good correlation between the arising of planar alignment and the existence of hydrogen bonds. We would like to underline that hydrogen bonding plays a very important role not only in the formation of mesophase([2]), but also in the interactions at the surface.
