It was found that the synclinic interlayer interactions for materials having mesogenic cores made of repeating benzyloxycarbonyl units are stronger than for the parent MHPOBC and analogous compounds having biphenyl-phenyl mesogenic cores, as evidenced by significantly broader range of the synclinic phase and less frequent appearance of anticlinic phases in the homologous series. The biaxiality of the three-layer structure of the SmC* Fil* phase was directly observed at the temperature where the optical pitch is spontaneously unwound. The ferrielectric phase structure is nearly Ising-like. The Ising structure is most probably enforced by strong interlayer quadrupole order, in materials in which the ferri-phase appears nearly 20 K below the SmA phase.
