Antiferroelectric behavior is not exhibited by the liquid crystalline phases of 1 , n = 10, 12, 14, 16. This indicates new prospects for novel polar materials. Antiferroelectric behavior in 1 is prevented by the polymeric structure (·· MoO … MoO··) of the mesophase and its hexagonal symmetry. The range of mesophase stability is 25–45 K, from about 95 to 141 °C.
