Photocontrollability of liquid crystal alignment by a self-assembled monolayer formed from azobenzene-containing tetracation through coulombic interactions
This paper describes an environmentally benign process to fabricate a photoaligning monolayer for surface-assisted liquid crystal photoalignment by the surface adsorption of an azobenzene-containing tetracationic adsorbate From its dilute aqueous solution through electrostatic interactions. The resulting adsorbed monolayer on a silica plate irradiated with linearly polarized 436 nm light was applicable to azimuthal LC photoalignment.
