Abstract

Two novel series of siloxane containing low molar mass liquid crystals have been synthesized and characterized by DSC, optical microscopy and x-ray scattering. The compounds have been shown to exhibit nematic, smectic A, and chiral smectic C phases. In this paper we concentrate on the unusual electro-optic threshold voltage and response time behavior of these materials in the S_A phase. Pleochroic and fluorescent dyes have been incorporated into mixtures and data is presented on the electro-optic properties of such guest-host materials.
