A ferroelectric side-chain liquid crystalline polysiloxane (FLCP) containing azobenzene dyes as guest molecules for electro-optics has been investigated. The intensity and frequency of the Goldstone mode for the FLCP were increased remarkably after doping with azobenzene dyes. Larger fluctuation of the spontaneous polarization vector in each smectic layer under an applied electric field can be brought...
Dielectric relaxation behaviour of the guest-host mixture of a ferroelectric side chain liquid crystalline polymer (FLCP) and a nonlinear optical (NLO) dye has been investigated with broadband dielectric relaxation spectroscopy. The liquid crystal (LC) phases of these guest-host materials were characterized with the differential scanning calorimeter, optical polarizing microscopy, and X-ray diffractometer...
