Clearing Point

A cholesteric liquid crystal cholesteryl nonanoate was synthesized and then characterized by means of differential scanning calorimetry and polarized optical microscopy. As temperature decreased from its clearing point, cholesteric phase was formed for cholesteryl nonanoate and accompanied by continuous evolution of colors in the focal conic textures. Furthermore, beautiful spherulite crystals were observed to grow out of the cholesteric phase as the crystallization continued. The evolution of the colors in recorded textures was contributed to temperature-dependent selective reflection of the liquid crystal.

Acid Unit

A series of liquid crystal monomers with side chains involving a vinylacetic acid unit have been prepared, and their thermal and optical properties compared with those of related compounds containing the same mesogenic unit but a conventional polymethylene spacer group based on a terminal alkene.
