Polymeric composites based on the copolymer butyl methacrylate: nonyl methacrylate (3:1) doped 8hydroxyquinoline azo dyes with donor and acceptor substitutes and their complexes with cobalt are obtained. The influence of the external electric field on the polymeric films transmission of linear polarized light in the long-wave part of the azo dyes absorption range, (corresponding !!* azo fragments absorption range) and their metal complexes are observed. The influence of the electric field on the transmission is connected with the aligning forces for dipole moments of azobenzene groups and metal ions.
