Synthesis and Characterization of Ionic Chiral Liquid Crystal Monomers and Assessment of their Contribution to Enhanced Performance of Polymer Stabilized Cholesterol Liquid Crystals
Abstract
The PI had good success with this grant. Ionic and chiral monomers were newly synthesized and applied for the development of polymer-stabilized CLC films which can be tuned by electric fields. The effect of ions in CLC films on the electro-optical properties was especially examined by varying critical parameters ranging from ionic interaction, network density, and helical twisting power. The acrylate function introduced both in ionic and chiral was helpful to securely preserve the self-assembled helical superstructures and to obtain the heterogeneous pitch distributions by the photo polymerization process. Information obtained in this project can be utilized to understand the dynamics of structure development and to better control responses. The large and reversible notch broadening had potential applications for full color displays, broadband polarizers and wave plates.
