• 論文の詳細を見る

• Mesomorphic properties are studied on the title compounds where substituents are F, Cl, Br, I, NO<SUB>2</SUB>, and CN. Besides the known mesophases, nematic and smectic Ad, in CN and NO<SUB>2</SUB> homologues, stable smectic A and B phases were observed in either of the Cl and Br derivatives. Metastable nematic and smectic A phases were found in F derivative. The effects of terminal polar substituents, stabilization of the smectic A phase by moderately polar substituents, and of the nematic phase by strongly polar substituents, were confirmed.
