The synthesis of a,ω-bis(4-p-phenylphenoxycarbonyl)phenoxyalkanes were described. A series of main-chain thermotropic polyesters which have an alternating sequence of mesogenic units and polymethylene spacers as well as their model compounds whth mesogenic units and spacers were investigated. Their liquid crystalline behavior, especially their thermal transition properties and nature of mesophases were compared with each other. The mesomorphic properties of the compounds were investigated by differential scanning calorimetry(DSC) and by polarizing microscopy.
