Photoinduced anisotropy measurements in liquid-crystalline azobenzene side-chain polyesters

By Holme, NCR; Ramanujam, P.S.1; Hvilsted, Søren

From

Risø National Laboratory for Sustainable Energy, Technical University of Denmark1

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.
