Photonic Crystals: Light-Patterned Crystallographic Direction of a Self-Organized 3D Soft Photonic Crystal (Adv. Mater. 42/2017)

The orientation of the crystallographic direction of a selforganized 3D soft lattice is "tamed" and tailored facilely by light irradiation, as described by Yan-Qing Lu, Guoqiang Li, Quan Li, and co-workers in article number 1703165. The designed photoalignment technique enables diverse micropatterning of the crystallographic direction of the cubic superstructure that can be readily erased and rewritten ondemand by light. The potential of the stimuli-responsive micropatterns is demonstrated in advanced reflective photonic applications.
