Liquid Crystalline Blue Phases for Electro-optical Devices

摘要

In this paper, we present the phase behavior and electric field-induced color shift of the dendritic molecule-sta bilized liquid crystalline blue phases. The electro-optical Kerr effect of the optically isotropic liquid crystal composites, which require no surface treatment for device fabrication are also presented. Anomalously large Kerr constant, more than 10~(-8) mV~2 and fast response, less than sub-milli-second are observed at a room temperature.
