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.
