Liquid Crystalline Phenyl‐trans‐4‐n‐alkylcyclohexanecarboxylates The syntheses of p‐substituted phenyl‐trans‐4‐n‐alkylcyclohexanecarboxylates 1–12 and cyclohexyl‐p‐n‐alkylbenzoates 15–17 and their mesomorphic properties are described. p‐n‐Alkoxyphenyl‐trans‐4‐n‐alkylcyclohexanecarboxylates 1–8 exhibit larger thermal stability of mesophases than analogous phenylbenzoates 13. Trans‐4‐subst. cyclohexyl‐p‐n‐alkylbenzoates 15–17 and S‐phenyl‐thiocylohexanecarboxylates 19 on the other side are less stable.

1,4-disubstituted cyclohexanes with transconfiguration and the N,N'-disubstituted piperazine system are able to function as a nucleus in liquid crystals. These characteristics are described in the case of nine homologous series (1-9) of corresponding compounds
