Abstract
A new series of polar mesogens exhibits both a smectic B phase and a ribbon phase Sc. In this series, an incommensurate hexatic B phase has also been found. In this phase, a long wavelength modulation of the dipolar orientation is superimposed over the in-layer 2D hexagonal array. The structural features of this new phase are compared to those of the normal hexatic B and Sc phasesKeywords
