- LIQUID CRYSTAL ORIENTATION ON VARIOUS SURFACES.
-
The liquid crystal orientation on various surfaces were investigated by using the ″Liquid Crystal Chromatography,″ which is useful for observing the true orientation by eliminating impurities in the liquid crystal materials. As the result, it was found that all nematic liquid crystals of Schiff base-, biphenyl-, ester-, PCH-, and azoxy-compounds aligned parallel to the surfaces of In//2O//3, Al//2O//3, soda-lime glass, SiO, etc. On the other hand, some of these liquid crystals such as MBBA, 5CB have been known to have a tendency to align perpendicular to the surface like In//2O//3. Then, the reason of this discrepancy was also investigated and it was found that impurities produced by hydrolysis of these liquid crystals had amphiphilic characteristic which induced a perpendicular alignment of these liquid crystals.

- Biphenyl esters and liquid crystalline mixtures comprising them
-
Biphenyl esters of the formula STR1 wherein X is --CO--O-- or --O--CO-- and R1 and R2 each are alkyl or alkoxy of 1 - 8 carbon atoms, enlarge significantly the temperature range of the nematic phase of liquid-crystalline compositions without adversely affecting other properties.
