Title:
TRANS-4-(TRANS-4'-ALKYLCYCLOHEXYL)CYCLOHEXYL PENTAFLUOROBENZOATE
Document Type and Number:
Japanese Patent JPS58150542
Kind Code:
A
Abstract:

NEW MATERIAL:A compound expressed by formulaI(R is 1W10C alkyl).

EXAMPLE: trans-4-(trans-4'-Ethylcyclohexyl)cyclohexyl pentafluorobenzoate.

USE: A component of a liquid crystal composition, drivable at a low voltage in spite of the small dielectric anisotropy, capable of reducing the power consumption of a display element and exhibiting the nematic phase in a wide temperature range, and having a low viscosity. The dielectric anisotropy value (Δ) ia about +2.

PROCESS: A compound expressed by formula II is reacted with a compound expressed by formula III in pyridine to give the compound, expressed by formulaI, particularly suitable for preparing a liquid crystal composition having a high N(nematic)-I(clear) point, and having the stability to heat, light, humidity, electricity, etc. necessary for a display element and further the tendency toward a lower viscosity on mixing with another product.
