Polymeric composites based on the butyl methacrylate: nonyl methacrylate (3:1) copolymer doped with 8-hydroxyquinoline azo dyes with donor and acceptor substituents and the cobalt complexes thereof have been obtained. The influence of an external electric field on the polymeric film transmission of linearly polarized light in the long-wave part of the azo dye absorption range (corresponding to ππ* azo fragment absorption range) and their metal complexes have been revealed. The influence of the electric field on the transmission is connected with the forces acting on dipole moments of azobenzene groups and metal ions.
