Fluorescent Guests in Thermotropic and Chirality in Lyotropic Liquid Crystals.
Abstract
Three problems were examined under this program. Firstly, a novel electro-optical display concept has been developed in our laboratory involving the incorporation of fluorescent (emissive) guest molecules into a cholesteric liquid crystal host. Improvements were made in the contrast ratios of such displays via electrochemical quenching. Secondly, a fundamental study was completed on the nature phase transitions in thermotropic liquid crystals confined in porous polymer films. Finally, new lyotropic fluid crystals were investigated to (a) try to develop non-aqueous lyotropic media, and (b) investigate orientational ordering and solubility of guest molecules in lyotropic nematics and cholesterics.
