We propose new structures of polymeric composites with changeable optical characteristics (transmission and/or reflection of polarized light) under the influence of magnetic and/or electric fields. The new monomers 4-methacroyloxy-(4'-carboxy-3'-hydroxy)-azobenzene, 4-methacroyloxy-(4'-carboxy-3'-hydroxy)-2-nitroazobenzene, and 4-methacroyloxy-(4'-carboxy-3'-hydroxy)-2-diethylamino-azobenzene, their complexes with Co, and polymers based oil their base are synthesized. The influence of the electric field on the absorption spectra of films of the new metal-containing azopolymers is investigated. The effect of an electric field on the transmission of a linearly polarized light through the films is revealed. This effect is determined by the re-orientation, of the dipole moments of azobenzene groups which is induced by a polarized light under the action of all electric field. The increase of the dipole moments of azobenzene groups clue to the introduction of donor and acceptor substituents reduces the influence of Co ions on the electrooptical properties of polymeric films.
