我们报道了液晶材料的合成，这些材料在室温下受到紫外线和可见光的照射后反复液化和固化。该材料是糖醇、D-甘露醇、D-山梨醇和大蒜醇的衍生物，其中所有的羟基都被多个介晶性偶氮苯取代。不同的糖醇改变了液晶相的热相变行为和稳定性，但光化学相变行为没有明显的差别。此外，当作为粘合层应用到玻璃基板上时，这些材料在受光照射时粘附力会发生变化。
We report the synthesis of liquid crystalline materials, which repeatedly liquefied and solidified when irradiated with ultraviolet (UV) and visible light at room temperature. The materials are the derivatives of the sugar alcohols, D-mannitol, D-sorbitol, and allitol, in which all hydroxyl groups were substituted with multi-mesogenic azobenzenes. The thermal phase transition behavior and stability of the liquid crystal phase were changed according to the sugar alcohols, but photochemical phase transition behaviors were not different. In addition, when applied as an adhesive layer to glass substrates, the materials exhibited changes in the adhesion force when irradiated with light.
