A homologous series of 4-alkoxyphenyl 3,4-di(4-alkoxybenzoyloxy)benzoates has been prepared.All the members (from the ethoxy to nonyloxy homologs) show a nematic phase having a fine schlieren texture, and the nonyloxy homolog also shows a smectic A phase

A new homologous series of 4-cyanophenyl 3,4-di(4-alkoxybenzoyloxy)benzoates (from ethoxy to decyloxy homologs) has been prepared.The homologs show both nematic and smectic A phases with fine schlieren and fan textures, respectively, whereas these have extremely large molecular breadth.The series is assumed to form an associated dimer and behave as a partially bilayer type smectic A phase.The dielectric properties have also been examined and the results support the formation of the associated dimer.The results have been discussed in terms of the geometry of the molecules.Keywords: mesomorphic properties; dielectric properties; polar liquid crystals; associated dimer.
