A new homologous series consisting of 12 homologues central azo, and ester linkage with chloro lateral group at central and methyl group at the terminal benzene ring is synthesized and their mesomorphic properties are studied. All the homologues are mesogenic in nature. All the compounds are exhibiting enantiotropic nematic phase; no homologues shows smectic phase even in monotropic form. To evaluate the effect of lateral chloro group at central benzene ring and methyl group at terminal benzene ring, the present series is compared with structurally related homologous series. The structure of the synthesized compounds is characterized by standard spectroscopic method, viz., IR, UV, NMR, and MASS.
