Synthesis and electrooptical properties of metal-containing azopolymers

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)-

Synthesis and electrooptical properties of metal-containing azopolymers. The influence of steric factors on the electro-optical effect in polycomplexes of azobenzene derivatives with cobalt

We propose new structures of metal-containing azopolymers with changeable electro-optical properties in consequence of different coordination metal ions. The new monomers - 4-methacroyloxy-(4'-carboxy-3'-hydroxy)-azobenzene, 4-methacroyloxy-2'-carboxy-azobenzene and their complexes with Co and polymers based of these ones are synthesized. The influence of the electric field on the absorption spectra of new metal-containing azopolymers films are investigated. Electro-optical properties of polymeric films is determined by the re-orientation of dipole moments of azobenzene groups photo induced by polarized light in the electric field. Increase of structural inflexibility by the photo isomerization of azobenzene groups decrease the electro-optical effect value.
