Optically anisotropic films of side-group liquid crystalline copolysiloxane doped with photochromic azobenzene and stilbene derivatives were prepared by using standard liquid crystal cells of 4 mum in thickness. The films were irradiated with high power density laser light with the electric field vector creating an angle equal to 45degrees with the initial optical axis of the samples. As a result of irradiation, the photoorientation of the photochromic molecules, and the cooperative reorientation of the copolysiloxane side groups occurred. In the case of the copolymer layers containing azobenzene, the optical axis was turned by an angle of 45degrees during sufficiently long irradiation. The angle of reorientation and the degree of anisotropy were determined for the irradiated areas of the samples.
