The Liquid-Crystalline Properties of Some Chiral Derivatives of the 4-n-Alkanoyloxbiphenyl-4′-Carboxylic Acids

Abstract A variety of chiral derivatives of some 4-n- alkanoyloxybiphenyl-4′-carboxylic acids were prepared in order to produce a number of structurally related homologous series of compounds. In this systematic study, the synthesis of a number of chiral 2-chloropropyl, 3-chlorobutyl, alkylether, and 1 -methylalkyl esters of these acids are reported. The liquid-crystalline and ferroelectric properties of these materials were also investigated and the results obtained are compared with those previously established for the closely related 1 -methylpropyl, 2-methylbutyl, and 3, 7-dimethyloctyl esters of the same acids.
