Abstract

The utility of the azobenzene-polyelectrolyte layer-by-layer (LBL) ultrathin films for controlling liquid crystal (LC) azimuthal alignment was demonstrated. The irradiation of a hybrid LC cell with linearly polarized light resulted in in-plane homogenous LC alignment dependent on the thickness, irradiation time and stability of the films. The direction of the LC molecules was found to be perpendicular to the polarization plane and could be reoriented.
