Liquid-Crystalline D-Glucose Dialkyl Acetals and Dodecyl D-Glucofuranosides

Two new systems of liquid crystalline glucose derivatives 5a‐d, 6a, b are prepared, studied and compared with reference compounds. The α‐ and β‐D‐dodecyl glucofuranosides 6a, b show smectic A phases. The clearing points of the furanosides are of the same magnitude as those of the pyranosides. The alkyl glucose acetals 5a‐d show columnar discotic phases. The clearing points are about 30°C lower than those of the corresponding thioacetals. Tietze*, L.F., Böge, K., Vill, V.
