They are some special chemicals for the production of liquid crystals. These chemicals are the research focus of liquid crystal polymers. Those synthetic polymers which has been commercialized include aromatic polyamide (Kevlar and etc.), thermotropic liquid crystalline copolyesters(Xydar, Vectra A and etc.) and thermotropic liquid-crystalline polyester-amides(Vectra B). Generally most of them have linear molecules. Their value is relatively high.

See the related link for information about 2-Bromo-4-fluorotoluene that are used as an intermediate of liquid crystal materials.
