Walton, HG and Coles, HJ (1993) Photomechanically induced phase transitions in ferroelectric liquid crystals. Ferroelectrics, 147. pp. 223-240. ISSN 0015-0193Full text not available from this repository.
We report optically induced phase transitions occurring in two different host ferroelectric liquid crystals. These act as host liquid crystals for a novel gust azo dye, which can be made to photoisomerise using low power density U.V. illumination, resulting in dramatic changes in sample properties. We have shown that the magnitude of spontaneous polarization of systems can be isothermally and reversibly induced or reduced, with the consequent appearance or disappearance of optical switching hysteresis.
