Eleven compounds of general structure R-X-Y-COO-Z-R', where X,Y and Z are either phenyl or trans cyclohexyl rings, were synthesized and their liquid crystalline properties were evaluated.The isomerization methods for cis-4-alkyl cyclohexanol to the trans isomer and for 4'-alkylphenyl-4-cis-cyclohexanecarboxylic acid to its trans isomer are discussed.The trans isomers were isolated and purified by preparative HPLC.The structure assignments were confirmed by carbon 13 NMR.
