Esters in the homologous series 4-alkoxyphenyl 4'-alkylbenzoates, 1a, have been synthesized with both straight and methyl-branched R-groups from C3-C6, plus n-C9 and n-C10 and with straight chain R'O-groups = C1-C8, C10, C12, C14 and C16. The mesophase transitions and properties were studied by hot-stage microscopy; DSC data were also determined for the R=C5 series. Comparisons within the la series and for some 4,4'-dialkylphenylbenzoates and 4-alkylphenyl 4'-alkoxybenzoates enable generalizations to be made regarding the liklihood of observing specific smectic mesophases as a function of structure.
