Some Features of Electro-Optical Properties of Polymeric Compositions Doped with 8-Hydroxyquinoline-Based Azo Dyes and Their Cobalt Complexes

摘要

Polymeric composites based on the copolymer butyl methacrylate: nonyl methacrylate (3:1) doped 8-hydroxyquinoline 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 longwave part of the azo dyes absorption range, (corresponding ππ~* 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.
