摘要：

Reversible photoinduced anisotropy in a series of Liquid-crystalline azobenzene side-chain polyesters is investigated as a function of intensity of the write beam and the sample temperature. Measurements reveal that the erasing takes place at a temperature much higher than the glass transition temperature. induced anisotropy can be erased by heating the polyesters to approximately 80 degrees C.
