Article abstract of DOI:10.1246/bcsj.59.3965

The homologous series of N-<4-(4-n-alkoxybenzoyloxy)benzylidene>-4-(2-methylbutoxy)aniline (1), and N-<4-<4-(2-methylbutoxy)benzoyloxy>benzylidene>-4-n-alkoxyaniline (2), and N-<4-(4-n-alkoxybenzoyloxy)-3-hydroxybenzylidene>-4-(2-methylbutoxy)aniline (3) where the 2-methylbutoxyl group has an S-configuration, have been prepared.Series 1 and 2 form a chiral smectic C (S^*_C) phase in addition to a cholesteric (Ch) and a chiral smectic G (S^*_G) phases, and series 3 form (S^*_C) and Ch phases.
