| Popis: | 6-O-α- d - Galactopyranosyl - d - glucopyranose (melibiose) derivatives with alkyl groups at the terminal 1- O and 6′- O positions have been synthesized. They show thermotropic and lyotropic liquid-crystal properties. The d -spacings of the strong inner X-ray diffraction rings correspond to ∼ 0.9 times the extended length of the molecule. The molecules are therefore either extended in monomolecular layers or U-shaped in bimolecular layers. |
