88. Photoinduced reorientation of polymethacrylate film with 4-methoxyazobenzene side groups using linearly polarized He-Ne laser and annealing, N. Kawatsuki, E. Uchida and H. Ono, Chem. Lett. 33 (2004)12-13.


This letter describes thermally enhanced reorientation of azobenzene-containing polymer .lms by linearly polarized (LP) 633 nm He\'96Ne laser light. Axis-selective photoreaction of the Z-isomers and subsequent annealing generated parallel reorientation with a reorientational order larger than +0.8 although the film was almost off-resonant at 633 nm.
