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]
