Stabilized by fluorine: For the first time a conclusive explanation for the beneficial effects of fluorine in aliphatic bridges within the mesogenic core structure of nematic liquid crystals is offered. A combination of steric and stereoelectronic effects stabilizes rod‐like conformations (see pciture) which are essential for the formation of the nematic phase.
