Bibliographic description in the original language

Annotation

Photoinduced dichroism (PD) in azo-containing polymers can result from chromophore orientation and/or cis-isomer accumulation. The PD formation mechanism of azochrommophores DO3 (DisperseOrange 3) doped in polymethyl methacrylate (PMMA) at a temperature varying from –20 to +120 ?C is studied by UV-visible spectroscopy. It is shown that the main PD formation mechanism at T < 0?C and T > 60?C is cis-isomer accumulation and trans-isomer photoorientation, respectively.

Keywords

chromophore, photo-induced dichroism, isomerization, photo-orientation.
