Abstract
NEW MATERIAL:A compound shown by the formulaI(R is 1W9C alkyl).
EXAMPLE: 4'-(β-Butyloxyethyl)-4-cyanoterphenyl.
USE: A liquid crystal compound. Having a positive dielectric anisotropy, a wide range of liquid crystal temperature, high transparent point, and improve stability. This compound alone can be used practically because of its high melting point, but its blending with other liquid crystal compound has an effect on the rise in transparent point.
PROCESS: For example, a compound shown by the formula X is reacted with a compound shown by the formula IX, to give a compound shown by the formula XI. This compound is then dehydrogenated with sulfur or cloranil to give a compound shown by the formula XII, which is reacted with CuCN, to give a compound shown by the formulaI.
