Abstract Different substituents (fluoro, chloro, bromo, and cyano) have been separately introduced into the 2-position of the phenolic moiety of the 4-n-alkylphenyl 4-n-alkylbicyclo (2.2. 2) octane-1-carboxylates to produce new series of low melting esters with large nematic ranges. In particular, thirty 4-n-alkyl-2-fluorophenyl and thirteen 4-n-alkyl-2- chlorlorophenyl 4-n-alkylbicyclo (2.2. 2) octane-1-carboxylates are reported. The effect of ...
