Abstract
NEW MATERIAL:3-(β-Alkyloxyethoxy)-6-hydroxyphthalonitrile esters of formula I [R1 is 1W5C alkyl; X is group of forumla II or III (R2 is 1W10C alkyl, alkyloxy)].
EXAMPLE: 3-( β-Ethoxyethoxy )-6-[ p-( trans-4-propylcyclohexyl )benzoyloxy ]-phthalonitrile.
USE: Liquid crystal material: they are mixed with other nematic compounds to form a liquid crystal with dielectric anisotropy of large negative value. It can be driven with a lower voltage than that necessary for conventional products.
PREPARATION: After the reaction of 2,3-dicyano-p-hydroquinone with a β-alkoxyethylation reagent such as β-alkoxyethyl bromide in the presence of an alkali, a compound of the formula: X-COCl is made to react with the product in a basic solvent such as pyridine to give the compound of formula I.
