摘要: 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 their mesomorphic properties are described. p-n-Alkoxyphenyl-trans-4-n-alkylcyclohexanecarboxylates 1–8 exhibit larger thermal stability mesophases than analogous phenylbenzoates 13. Trans-4-subst. S-phenyl-thiocylohexanecarboxylates 19 on the other side less stable.
