Popis:	A bifurcated and an open chain (linear) can be introduced laterally into mesogens containing four rings in the main core. The racemic compounds give a narrow nematic range. The X-ray crystal structures of two isomeric compounds show that the bifurcated chain is not aligned along the core as the linear one is. This unfavourable arrangement may be the cause of the deleterious effect of the bifurcated chain on the nematic range.
