Abstract

Abstract : Jeroen Beeckman and co‐workers (see article number1701163 ) have developed a liquid crystal photo‐alignment method in which the polar and azimuthal anchoring are determined by the intensity and the polarization of the UV illumination. Patterned UV illumination of the two‐component alignment layer yields surfaces with periodic stripes of planar and homeotropic anchoring. The interplay between the patterned surface anchoring and the chirality of the liquid crystal leads to the formation of new chiral superstructures.
