Bicyclo[2.2.2]octane esters exhibiting wide-range nematic phases

Abstract

Three types of ester incorporating the 1,4-disubstituted bicyclo[2.2.2]octane ring have been prepared and found to exhibit wide-range nematic phases at higher temperatures than those of analogous mesogens containing the 1,4-disubstituted phenylene or trans-1,4-disubstituted cyclohexane ring.
