超膨潤スメクチック相におけるC-directorの配向相関に対する溶媒効果

抄録

We introduced perfluorinated oil between the layers up to 50wt% in a smectic C liquid crystal having perfluorinated chain, called it “a hyper swollen smectic liquid crystal”, and investigated the swelling effect on the interlayer C-director correlation by dynamic light scattering measurement. It was found that the twist elastic constant related to interlayer C-director correlation strongly decreases in the hyper swollen smectic liquid crystal. This result suggests that perfluorinated oil prevents the direct collisions between layers among liquid crystal molecules, hence the interaction to maintain the interlayer C-director correlation between layers is weakened by the swelling effect.
