A series of para substituted trans-4-alkylcyclohexylbenzylamines was prepd. and examd. for mesomorphic properties. The n-pentyl deriv. showed monotropic smectic behavior while the n-heptyl deriv. was an enantiotropic smectic. These are examples of low temp. liq. crystals incorporating an amino functionality. While the p-(trans-4-alkylcycloxexyl)anilines were not liq. crystalline, N-alkyl substituted-p-(trans-4-pentylcyclohexyl)anilines, such as N- (butyl)-p-(trans-4-pentylcyclohexyl) aniline exhibit low-temp. mesophases. A strong tendency to spontaneous homeotropic alignment was found in the nematic members of this series. Chem. Abstr. Vol 92, 138962w
