We investigate the dichroism characteristics of poly (methyl methacrylate) PMMA thin films doped with DO11, DO3, DSR13 and DSR1 dye molecules, which change under illumination with visible light. Our data show that photoisomerisation, phototautomerization reactions and light-induced polar orientation are dependent on the molecular structure of the polymer. Polar structure and molecular size, as well as the chemical structure of PMMA host, are the dominant parameters that determine both the extent and speed of dichroism buildup and relaxation processes. Two forms of DO11 molecules (keto and enol forms), and two other forms of azo-based dyes ( trans and cis forms) are responsible for the interaction with irradiating laser light and forming an anisotropic structure inside the PMMA/dye thin films.
