Abstract

Abstract: Anew series of ester-ether liquid crystal compounds with oligo(oxyethylene) mid-dle units has been synthesized by using 4-(4′-alkoxybenzoyloxy)benzoic acids as a liquid crystaLINtermediate. Chemical structures and liquid crystal behavior of the compounds were characterized by elemental analysis, ₁HNMR spectroscopy, DSCand polarizing microscopy. All the compounds, except Ⅰf, exhibit thermotropic liquid crystalline properties.

Key words: Liquid crystal, Ester-ether liquid crystal, Oxyethylene glycol bis[4-(4′-alkoxy-benzoyloxy)benzoate]
