Abstract

Ferroelectric (chiral) smectic C* liquid crystals have been shown to exhibit high speed, multistate electro-optic, display device and opto-electronic computing applications, particularly when incorporated into the surface stabilized ferroelectric liquid crystal (SSFLC) light valve. High polarizations and low viscosities are necessary to achieve the speeds desired in opto- electronic computing, waveguide, and fiber-optic applications. Use of the Boulder Model allows one to examine the most probable conformations of an FLC molecule in a hypothetical smectic C 'binding site' and thereby predict the sign and order of magnitude of the spontaneous polarization based on electronic and steric arguments for the particular chemical structure. By combining these high polarization materials with a low viscosity smectic C host, fast FLC mixtures can be formulated.
