Liquid crystal compound |
| abstract |
NEW MATERIAL:The compound of formula I (R 1 and R 2 are 1W20C straight- chain alkyl; ring H is cyclohexane ring; X is H or halogen). n EXAMPLE: 4-[2'-(4"-trans-n-Propylcyclohexyl)ethyl]phenyl 4'''-decyloxy3'''-fluoro benzoate. n USE: A substance for liquid crystal display element. An optical switching element. It has ferroelectric smectic C phase and exhibits low viscosity. n PREPARATION: The compound of formula I can be produced by the ester condensation of a compound of formula II with a compound of formula III. The ester condensation is carried out by converting the compound of formula III to corresponding acid chloride with a chlorination agent such as thionyl chloride and condensing the acid chloride in the presence of pyridine, triethylamine, etc. n COPYRIGHT: (C)1988,JPO&Japio |
