Abstract
A homologous series of chiral swallow‐tailed materials with a methleneoxy linking group, 1‐ethylpropyl (S)‐2‐{6‐[4‐(4‐alkoxyphenyl)benzyloxy]‐2‐naphthyl}propionates, EmPNP (m = 8–12), has been synthesized for investigation. Polarizing optical microscopy observations demonstrated that the materials exhibit a N* phase and two frustrated phases: the twist grain boundary smectic A* (TGBA*) and smectic C* (TGBC*) phases. All of the materials exhibit a wide TGB phase temperature range. The spontaneous polarization and apparent tilt angle of the TGBC* phase for compounds in surface stabilized geometry in 5 µm homogeneously aligned cells were also measured and reported.
