The invention relates to novel compounds usable as liquid crystals in liquid crystal display devices utilizing the electrically controlled birefringence effect. These compounds comply with formula: STR1 in which R1 represents an alkoxy or alkyl radical with 1 to 12 carbon atoms and Z represents a single bond or a radical chosen from among: STR2 provided that R1 represents an alkyl radical when Z represents a single bond and R2 represents an alkyl radical with 1 to 12 carbon atoms. They can be obtained by reacting an acid chloride of formula R1 --z--COCL with a 2,2'-difluoro-4-alkoxy-4'-hydroxydiphenyl of formula: STR3

A number of homologs of 4-substituted phenyl 4'-(4-alkylbicyclo-octylcarbonyloxy)benzoates were synthesized, which form a liquid crystalline state of the nonmagnetic type.The obtained compounds have higher melting points and transition points to the isotropic state than the analogous 4-alkylbenzoic acid derivatives; in their dielectric constants they are close to the related 4-alkylcyclohexanecarboxylic acid derivatives and differ sharply from the 4-alkylbenzoic acid derivatives.
LIQUID CRYSTAL PROPERTIES OF 4-n-ALKYL- AND 4-n-ALKOXY-PHENYL 4-n-ALKYLBICYCLO(2. 2. 2)OCTANE-1-CARBOXYLATES.

Two new series of esters incorporating the 1,4-disubstituted bicyclo(2. 2. 2)octane ring system are reported. Thirty-three 4-n-alkylphenyl 4-n-alkylbicyclo(2. 2. 2)octane-1-carboxylates and thirty 4-n-alkoxyphenyl 4-n-alkylbicyclo(2. 2. 2)octane-1-carboxylates have been prepared and found to exhibit wide-range nematic phases persisting until higher temperatures than those of the corresponding esters containing either the trans-1,4-disubstituted cyclohexane ring or the 1,4-disubstituted benzene ring in place of the bicyclo-octane ring. Mixtures of these novel bicyclo-octane esters with cyanobiphenyls have been found to be superior for multiplexing applications in twisted nematic cells to equivalent mixtures employing 4-n-alkylphenyl 4-n-alkoxybenzoates or 4-n-alkoxyphenyl trans-4-n-alkylcyclohexane-1-carboxylates.
