| Research Abstract |
Liquid crystalline (LC) polymer brushes containing an azobenzene (Az) mesogenic moiety on a quartz or silicon substrate are prepared by surface initiated atom transfer radical polymerization (ATRP). The grafted chain film adopted a smectec LC phase and the molecular orientation of Az mesogens in the grafted chain was parallel to the substrate plane. Highly ordered in-plane photoalignment of Az mesogens in the grafted chain was readily provided by the irradiation with linearly polarized visible light due to the effective light absorption of the Az mesogens aligned parallel to the substrate.
