Abstract
Reversible photoinduced anisotropy in a series of Liquid-crystalline a zobenzene side-chain polyesters is investigated as a function of inten sity of the write beam and the sample temperature. Measurements reveal that the erasing takes place at a temperature much higher than the gl ass transition temperature. induced anisotropy can be erased by heatin g the polyesters to approximately 80 degrees C.
