<br/><br/> Two groups of laterally-methyl substituted compounds having the formulae, 4-(4'-hexyloxy) phenylazo-2-(and 3) methyl phenyl 4"-substituted benzoates (a-e and a-e) were prepared and investigated for their mesophase behavior. Each group consists of five derivatives that differ from each other by the terminal polar substituent  which varies between CH₃O,CH₃, Br, NO₂, and CN
