摘要：

A macroscopic study of chiral smectic-O* films, which float at the free surface of isotropic droplets of 1(methyl)-heptyl-terephtalidene-bis-amino cinnamate, is presented. It allows us to directly prove antiferroelectricity with in-plane polarization in the smectic-O* phase, and to confirm the herringbone structure of this original phase. The bulk antiferroelectric polarization is measured to be about 0.1 D per molecule.
