Synthesis of Non-symmetrical Dimeric Liquid Crystals and Their Phase Transition Behavior(III)

Synthesis and Characterization of Non-symmetrical Dimeric Liquid Crystals Including Fluorinated Mesogenic and Cholesteryl Groups

Abstract

A new non-symmetrical dimeric liquid crystal including two distinct mesogenic groups, 4-(4-fluorobenzoyloxy)phenyl cholesteryl decanedioate was synthesized and the mesomorphic properties were studied by a differential scanning calorimeter and a polarizing microscope. In addition, analogous compounds were synthesized with changing the position and/or the number of fluorine substituents, and the mesomorphic properties of these compounds were studied by the same methods in order to investigate the effects of fluorine substituents.
