Inside Cover: Brightly Tricolored Mechanochromic Luminescence from a Single-Luminophore Liquid Crystal: Reversible Writing and Erasing of Images (Angew. Chem. Int. Ed. 39/2011)



original image

A mechano- and thermoresponsive luminescent liquid-crystalline material that has a single luminophore group and shows three distinct colors of reddish-orange, yellow, and green is described by Y. Sagara and T. Kato in their Communication on page 9128 ff. Mechanically induced isothermal and thermal phase transitions accompany the switching of the nanostructures formed by the liquid crystal and lead to a change in the intermolecular interactions.
