Synthesis and Electro-optical Properties of New Liquid Crystals Having and Aliphatic Trifluoromethyl Ether Moiety as a Polar Function

Abstract

The oxidative desulfurization-fluorination reaction of xanthates was applied to the synthesis of new type liquid crystals (LCs) having an aliphatic trifluoromethyl ether moiety as ,a polar function. The novel LCs were shown to exhibit mesophases in wide a range of temperatures and decrease birefringence and threshold voltage of host nematic LCs upon mixing by 20 wt%.
