The Synthesis and Transition Temperatures of Ester Derivatives of 2-Fluoro-4-hydroxy- and 3-Fluoro-4-hydroxybenzonitriles also Incorporating Aliphatic Ring Systems

The synthesis and liquid-crystal transition temperatures of forty ester derivatives of 2-fluoro-4-hydroxybenzonitrile and 3-fluoro-4-hydroxybenzonitrile are reported.The esters contain the trans-1,4-disubstituted cyclohexane or the 1,4-disubstituted bicyclooctane rings (some contain an additional phenyl ring).Many of the novel F-substituted esters exhibit substantially higher nematic-isotropic transition temperatures than the corresponding unsubstituted esters.The order of clearing points of these laterally substituted esters differing only in the presence of a benzene ring and the above-mentioned rings is established.
