Abstract

Electrooptic measurements were performed on a lamellar nematic phase in which the mesogenic moieties lie in lamellae that are separated by partially perfluorinated side groups. The twist elastic constant K22 and the quadratic and quartic anchoring strength coefficients are reported. K22 is found to be considerably smaller than that of typical three-dimensional nematics, a con- sequence of the greatly weakened interactions between the spatially separated lamellae.
