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.
