Photocontrolled Alignment of Chiral Nematic Liquid Crystals
Source abstract
Abstract
The first successful alignment of helix axes of chiral nematic liquid crystals (LCs) by the photoalignment technique is reported here. The helix axis aligns perpendicularly to the propagation direction of the incident non-polarized light. Dark and bright images (see Figure) of the aligned helix axis of a chiral nematic LC are reversed by rotating the crossed polarizers at 45°.
