Abstract
The preparation and liquid crystalline properties of twenty-nine trans-decalin-2-carboxylates are described and the esters are found to exhibit wide-range smectic and nematic phases persisting until higher temperatures than those of the corresponding esters containing the trans-1,4-disubstituted cyclohexane ring. Compared with analogous naphthalene-2-carboxylates, the clearing points are a little lower, but the melting points are considerably decreased; as a consequence, the decalin esters possess wider mesomorphic temperature ranges.
