Photoinduced three-dimensional orientational order in side chain liquid crystalline azopolymers

Abstract: We apply experimental technique based on the combination of methods dealing with principal refractive indices and absorption coefficients to study the photoinduced 3D orientational order in the films of liquid crystalline (LC) azopolymers. The technique is used to identify 3D orientational configurations of trans azobenzene chromophores and to characterize the degree of ordering in terms of order parameters. We study two types of LC azopolymers which form structures with preferred in-plane and out-of-plane ali… Show more

“…Yaroshchuk and coworkers investigated three-dimensional molecular alignments in azobenzene LCPs [195,196]. Various states of optical anisotropy can be induced by photoirradiation using two-different wavelengths of polarized light, which is illustrated by three-dimensional index ellipsoid at uniaxial and biaxial in the literatures.…”
