Abstract:

A new series of nematic liquid crystals based on p-alkylcarbonato-p- alkoxyphenyl benzoates was prepared. Binary and ternary mixtures of selected derivatives taken from this series exhibited nematic behavior at or near room temperature. These materials were found to exhibit a highly efficient scattering system with a gated ac signal at 120 V. A study of the orientation pattern of domain formation and the generation of disclination loops was undertaken in an effort to further elucidate the mechanism of dynamic scattering. A practical and useful technique for the sealing and encapsulation of liquid crystal cells was developed. This procedure was applied to the fabrication of two numeric indicators and a transmission window which were furnished under the contract.
