The liquid-crystalline properties of some chiral derivatives of the 4-n-alkanoyloxybiphenyl-4'-carboxylic acids.
01 January 1988
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.
