Paper No S3.2: Chiral Mesomorphic Compounds and Materials for Display Applications

In this paper, we describe the effect of the molecular structure of chiral anisotropic compounds and materials on their mesomorphic and physico chemical properties. Modifications of the molecules via cyclic and bridge fragments or via lateral substituents allowed the preparation and optimization of specific mixtures for different display applications. The formation of defect free layers in ferroelectric liquid crystals stable against various mechanical or temperature deformations was studied. A new electro-optic effect based on chiral-nematic mixtures for creating high-speed devices with switching time less than 1 ms was developed.
