摘要:

Induction and relaxation of optical anisotropy in azobenzene containing polymer films under the action of polarized UV-light irradiation are investigated by polarization UV and IR spectroscopy methods. The dependence of anisotropy relaxation on the exposure conditions is established. The results are interpreted supposing the partial ordering of main-chains fragments in irradiated films. A theoretical model explaining experimental results is developed.
