Abstract
Methods of forming a liquid crystal blue phase from composite materials comprising a chiral nematic liquid crystal host and an azobenzene-based bent-shape molecule are described. The composite materials quickly transfer from the liquid crystal blue phase to an isotropic phase under electromagnetic radiation and transfer from the isotropic phase to the liquid crystal blue phase when electromagnetic radiation is removed.
