Cover Picture: Bistable Nematic Liquid Crystals with Self-Assembled Fibers (Adv. Mater. 6/2005)



The cover shows a recording process using nematic liquid crystal alignment. On p. 692, Kato and co-workers report that reversibly bistable states have been achieved for nematic liquid crystals incorporating a small amount of self-assembled fibers. Homeotropic monodomains and non-aligned multidomains can be fixed and switched by thermal treatment in electric fields. The technique is applied to the formation of rewritable light scattering patterns, as shown on the cover.
