Abstract
NEW MATERIAL:A compound of formulaI(R1, R2 are 1W8C straight-chain alkyl).
EXAMPLE: p-(4'-n-Propylcyclohexyl)phenyl 4-n-butylcyclohexyl carbonate.
USE: Liquid crystal composition: it has relatively small Δ n and a wide range of liquid crystal temperature and shows very excellent characteristics as a material for phase-transition type GH-cells.
PREPARATION: 4-(4'-n-Alkylcyclohexyl)aniline of formula II is mixed with 70% sulfuric acid and aqueous sodium nitrite is added to form a diazo-sulfate solution. Then, it is hydrolyzed to give 4-(4'-n-alkylcyclohexyl)phenol of formula III. Further, 4-n-alkylcyclohexylcarbonyl chloride of formula IV is esterified in pyridine to form the compound of formulaI.
