LIQUID-CRYSTAL COMPOUNDS INCORPORATING THE TRANS-1,4-SUBSTITUTED CYCLOHEXANE RING-SYSTEM

A number of esters and other compounds containing a trans-1,4-substituted cyclohexane ring system have been prepared, and the liquid crystal thermal stabilities of these new mesogens are discussed in relation to those of their analogues containing the 1,4-phenylene ring. The observed effects are discussed in terms of a possible thermal energy absorption by the cyclohexane ring in causing minor conformational changes. Other physical properties of these new mesogens are also discussed with particular reference to their potential in applications. 23 refs.
