A homologous series 4-acetyl-2',4'-bis (4-n-alkoxybenzoyloxy) azobenzenes of eleven homologues has been synthesized by fixing 4-acetyl phenyl azo group to resorcinol moiety. Both the terminal and lateral hydroxyl group were esterified by 4-n-alkoxy groups. All the members of the series are monotropic/enantiotropic nematogens with the exception of the first member. The members of the series were characterized by standard spectroscopic methods, DSC, and optical microscopy. The mesomorphic properties of the present series are compared with other structurally related series.
