Cover Picture: A Novel Method for Fixing the Anisotropic Orientation of Dispersed Organic Nanocrystals in a Magnetic Field (Adv. Mater. 2/2005)



The cover illustrates trans-4-[4-(dimethylamino)]stilbazolium p-toluenesulfonate (DAST) nanocrystals as white rectangular parallelepipeds anisotropically oriented by an applied magnetic field. As reported by Kaneko and co-workers on p. 160, the oriented DAST nanocrystals dispersed in lauryl acrylate monomer can be easily fixed by UV curing in a magnetic field. The inset displays a picture of the cured DAST dispersions with a quarter for scale.
