    Abstract: A homologous series of chiral liquid crystal compounds, N‐methyl‐N‐pentyl‐(S)‐2‐(6‐(4‐(4‐alkyloxyphenyl)benzoyloxy)‐2‐naphthyl)propionamide, with an amide linkage in a chiral tail was synthesized and their mesomorphic properties studied. All the materials possessed an antiferroelectric smectic C (SmCA*) phase, which was confirmed by observations of microscopic texture, switching current behaviour and electro‐optical responses. The spontaneous polarization, P s, and apparent tilt angle, θ, were also measured. The maximum P s values are in the range of 173–222 nC cm−2, and the maximum θ values are in the range of 26–30°.
