520			_aTwo groups of laterally-methyl substituted compounds having the formulae, 4-(4'-hexyloxy) phenylazo-2-(and 3) methyl phenyl 4"-substituted benzoates ({u2160}a-e and {u2161}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 {u2169} which varies between CH₃O,CH₃, Br, NO₂, and CN
