    Photoorientation phenomena and structural properties of photochromic liquid crystalline azobenzene-containing polymethacrylate films with different spacer lengths

  • Original language description

    Azobenzene-containing liquid crystalline (LC) side-chain polymers belong to unique type of the “smart” macromolecular systems combining photochromism with self-assembly of chromophores and ability to form stable films, fibers and coatings. Two new azobenzene containing monomers were designed and characterized. Herein we describe synthesis and investigation of the phase behaviour and photo-optical properties of two chiral LC polymers with azobenzene-containing side groups having different spacer length. Irradiation by polarized light (457 nm) results in photoorientation process in polymer films consequential in significant alignment of the chromophores in direction perpendicular to the polarization plane of the incident light. A significant difference was found in thermal stability of the photoinduced alignment, an annealing of irradiated samples results in a slight decrease of dichroism values, whereas the dichroism increases for PMAzo-6 polymethacrylate.
