Outline of Final Research Achievements

We designed and synthesized novel sulfur-containing rod-like liquid crystalline molecules, and investigated their phase transition behavior and mesogenic structures in detail. Many of the obtained compounds show fluid nematic phase which is important for optical materials. In addition, it was found that they exhibit the proximity of neighboring molecules, larger increasing degree of order parameter and birefringence with respect to temperature, compared with alkyl and alkoxy analogs. They are ascribed to the intermolecular attractive interactin derived from sulfur atoms of the neighboring molecules.
