Abstract
NEW MATERIAL:The liquid crystal compound of formula I (R<1> and R<2> are independently 1-20C straight or branched chain alkyl; Z is single bond or ether bond; the ring A is phenyl or cyclohexyl which may be substituted with halogen; X is H or halogen). EXAMPLE:3,3'-Difluoro-4-hydroxy-4'-decyloxybiphenyl. USE:Useful as a component for liquid crystal composition and light-switching element. It has low viscosity, contains smectic C phase and is utilizable as a raw material for liquid crystal material having ferroelectric property. PREPARATION:The compound of formula I is produced by, according to the reaction formula, converting a compound of formula II to a corresponding acid chloride and subjecting the product to ester condensation reaction with a compound of formula III in a basic solvent such as pyridine.
