摘要：

A new series of chiral materials, hexy](2s)-2-(6-(-4-(4'-alkoxyphenyl)benz propionates (HmPBNP; m = 6-18) had been prepared and their liquid crystalline properties were investigated as a function of alkyl chain length. These chiral materials exhibited novel ferroelectric S-c* and antiferroelectric Sc-A* phases and a propensity to the formation of the Sc-A* phase was found at longer alkyl chain lengths (m = 10, 12-18). An odd-even effect of the threshold voltage as a function of alkyl chain length for compounds HmPBNP (m = 12-16) possessing antiferroelectricity was observed. Spontaneous polarization and trans verse dipole moment were also measured and are discussed in terms of the elongated alkyl chain length.
