Synthesis and Dielectric Investigations of New Swallow-Tailed Monomers and Polymers
A new class of liquid crystalline side chain polymers using swallow-tailed mesogens was synthesized. Comparative dielectric investigations on these polymers and on the corresponding low molecular weight substances in the frequency range from 10 Hz to 100 kHz should give information about the dynamic behaviour. The results obtained from the monomers agree well with those of other swallow-tailed liquid crystals and can be explained by an antiparallel orientation of the molecules in the S(A) phase. There are hints to a tendency to an antiparallel orientation of the side chains in the polymers, too.
