Photoinduced spatial orientational order in methacrylic thiazole containing azopolymers

The new copolymers methyl methacrylate and methacrylic azomonomers contained the tiazole ring in azofragments were synthesized. The combination of the transmission null ellipsometry and total absorption method is applied to study 3D orientational configurations of azochromophores in these polymethacrylates. Under irradiation, if reorientation mechanism of the photoinduced ordering prevails, the azochromophores reorient perpendicularly to the polarization direction of the exciting light, Eex.
