Using the same strategy, photoresponsive glassy liquid crystals were also obtained using dithienylethene moieties [327]. [Pg.139]

A final remark will concern the glassy liquid crystal . All the textures observed in the nematic state can easily be quenched and supercooled to room temperature. In spite of the thermal shock, both the planar alignment and the homeotropic one can be retained in the glassy state [59, 60, 66, 95]. [Pg.114]
