Cyclic liquid crystalline siloxanes (CLCS) are optical uniaxial positive (SA, N) and negative (N*) materials in accordance with calamitic structures.X-Ray measurements indicate, that the distances of SA layers correspond with the length of the monomer unit.In the case of mesogens with high polarity the distance is 1.7 fold the length of the monomer unit.A bundle model is proposed for CLC siloxanes.
