X-Ray Diffraction Studies on Alicyclic Saturated Discotic Liquid Crystals

Neuling, H. W.; Stegemeyer, H.; Praefcke, K.; Kohne, B.

The discotic liquid crystalline phase of a new class of disc-like molecules (hexa-O-alkanoylscyllo- inositoles) is studied by small angle X-ray scattering, DSC and optical observations. Comparison of these three methods allows the determination of the structural arrangement. X-ray film exposures of oriented samples clearly demonstrate the hexagonal columnar ordered type of mesophases. A simple model calculation shows that the alkyl chains of neighbouring columns interpenetrate each other to a small extent.
