Hydroquinone was esterified with 4-alkyloxybenzoic acid at one end and 3,4-dialkyloxy benzoic acid at the other end. Narrow nematic and smectic C phases were observed for the obtained homologues as compared to those of di(4-alkyloxy)benzoic acid esters. This was attributed to the substitution at the 3-position of the benzoic acid moiety.
