A novel mesogenic ester homologous series is synthesized and studied with a view to understanding and establishing the effect of laterally substituted -OCH3 on mesomorphic behavior. The series consists of twelve members. C-1 to C-4 members are nonmesogenic, C-6 to C-12 are smectogenic in addition to nematogenic, and C-14 to C-16 are only smectogenic. The textures of smectic and nematic phases are A or C type and threaded or Schlieren, respectively. The transition curves in a phase diagram exhibit an odd-even effect and behave in normal manner except for the C-14 and C-16 derivatives in Sm-I transitions. Thermometric data were determined by an optical polarizing microscope equipped with a heating stage. Average thermal stability for smectic and nematic are 107.7 degrees C and 121.0 degrees C, respectively. Smectogenic and nematogenic mesophase length ranges from 11.0 to 44.0 degrees C and 12.0 degrees C to 39.0 degrees C, respectively. The mesomorphic properties of present series are compared with structurally similar other known series. Thus, present series is predominantly smectogenic and partly nematogenic of middle ordered melting type.
