This paper discusses the absorption spectra of films of new azopolymers and polycomplexes of azobenzene derivatives with cobalt before and during the switching on of an electric field. It has been detected that an external electric field affects the transmission by the films of plane-polarized light at the long-wavelength absorption edge. This effect is caused by spatial reorientation of the dipole moments of azobenzene groups, photoinduced by polarized light in an external electric field. The fact that an electric field affects the transmission of light is explained by the appearance of forces that act on the dipole moments of the azobenzene groups and on the metal ions. The increase of the dipole moment of the azobenzene groups when donor or acceptor substituents are introduced into their composition reduces the influence of metal ions on the electrooptic properties of the polycomplex films.
