Ten members of a chiral homologous series 4-(4′-n-alkoxy benzoyloxy benzoyl) 4 ″-S-(+) 2-methyl butoxy anilides were synthesized in multiple step synthesis. Series exhibits chiral smectic* C and cholesteric mesophases. In this series, n-propyl to n-dodecyl derivatives exhibit smectic* C and cholesteric mesophases. n-Tetradecyl and n-hexadecyl derivatives exhibit only smectic* C phases. The plot of transition temperatures versus number of ...
