Abstract

Low-molecular liquid crystals containing silicon were synthesized. Concerning the purpose of the silicon tow aspects are of interest. Firstly, short siloxane segments are terminally attached to the mesogens which have a rod- like shape or a wedge-like one. This allows us to study the effect of opposite forces, especially of steric interaction and separation tendency, on the mesophase behavior. For the siloxan containing rod-like mesogens it can be observed that the smectic layers consist of two sublayers separating the incompatible moieties of the compounds. Secondly, the silicon is used as sp³ hybridized branching point to introduce three alkyl chains at one terminal position of the molecules.
