Structure-property correlations of new materials comprising of a cyclic enone for TFT-LCD applications

Abstract

Dielectric, birefringence and voltage-transmission characteristics of novel cyclic enone compounds are reported. The new materials are shown to exhibit high dielectric anisotropies and modest refractive index anisotropies. These results are explained by structural and substituent effects and are in accordance with the results expected from molecular modelling. The analogy found between structural and physical properties may be used to design improved materials for TFT-LCDs. The use of cyclic enones as dopants to contribute to a reduction in the threshold voltage of liquid crystal mixtures for TFT-LCDs is foreseeable.
