Since ferroelectric liquid crystals (FLCs) show a fast response to electric field, they are highly expected to be applicable in the photorefractive (PR) effect and optical devices.We synthesized a novel chiral dopant “COOT3-88” that bears a strong chiral isosorbide-core and a photoconductive tertiophene moiety. Our test with a nematic host LC (7OCB) has shown that depending on the temperature, COOT3-88 has a very strong helical twisting power (HTP) of 80~100 μm-1, as expected for an axial chirality. The spontaneous polarization in the FLCs induced by COOT3-88 and the photorefractive effect using COOT3-88 are under investigation.
