Paper Abstract

Two guest dyes are used to change dramatically the torque exerted by DC and optical frequency electric fields on ferroelectric and nematic liquid crystal hosts. The particularity of the photoisomerization mechanisms of these dyes is responsible for the unusual behavior of the guest- host compounds. Corresponding molecular model is provided by describe the photoexcitation of dyes and its influence on the host material.
