Abstract
Chiral smectic A electroclinic liquid crystalline materials are prime candidates for electrooptic applications because of their gray scale capability and fast dynamic response. The evolution of this technology greatly depends on the development of chiral smectic A materials with large induced tilt angles, field-independent fast switching times and a broad operating temperature range. We report in this paper the physical properties of a series of liquid crystal materials. Features of this series of materials are broad smectic A phase range and large induced tilt angles. Such large electroclinic coefficients make these materials good candidates of the development of silicon based reflective displays. Comparison of the electrooptic performance of the materials in SmA mesophase will be discussed.
