Investigation of Photoinduced Orientation Ordering in Polymethacrylates with Side-Chain Azobenzene Moieties

The initial and the photoinduced 3D orientational order in the films of two methacrylic polymers containing azobenzene groups with electron-donor or electron-acceptor substituents was studied by using null ellipsometry and UV/Vis absorption spectroscopy. The 3D order was induced by monochromatic polarized light of two different wavelengths corresponding to * and n* absorption bands of azochromophores.
